8 bool "Network device support"
10 You can say N here if you don't intend to connect your Linux box to
11 any other computer at all.
13 You'll have to say Y if your computer contains a network card that
14 you want to use under Linux. If you are going to run SLIP or PPP over
15 telephone line or null modem cable you need say Y here. Connecting
16 two machines with parallel ports using PLIP needs this, as well as
17 AX.25/KISS for sending Internet traffic over amateur radio links.

25 # that for each of the symbols.
29 tristate "Intermediate Functional Block support"
30 depends on NET_CLS_ACT
32 This is an intermediate driver that allows sharing of
34 To compile this driver as a module, choose M here: the module
35 will be called ifb. If you want to use more than one ifb
36 device at a time, you need to compile this driver as a module.
37 Instead of 'ifb', the devices will then be called 'ifb0',
39 Look at the iproute2 documentation directory for usage etc
42 tristate "Dummy net driver support"
44 This is essentially a bit-bucket device (i.e. traffic you send to
45 this device is consigned into oblivion) with a configurable IP
46 address. It is most commonly used in order to make your currently
47 inactive SLIP address seem like a real address for local programs.
48 If you use SLIP or PPP, you might want to say Y here. Since this
49 thing often comes in handy, the default is Y. It won't enlarge your
50 kernel either. What a deal. Read about it in the Network
51 Administrator's Guide, available from
52 <http://www.tldp.org/docs.html#guide>.
54 To compile this driver as a module, choose M here: the module
55 will be called dummy. If you want to use more than one dummy
56 device at a time, you need to compile this driver as a module.
57 Instead of 'dummy', the devices will then be called 'dummy0',
61 tristate "Bonding driver support"
63 depends on IPV6 || IPV6=n
65 Say 'Y' or 'M' if you wish to be able to 'bond' multiple Ethernet
66 Channels together. This is called 'Etherchannel' by Cisco,
67 'Trunking' by Sun, 802.3ad by the IEEE, and 'Bonding' in Linux.
69 The driver supports multiple bonding modes to allow for both high
70 performance and high availability operation.
72 Refer to <file:Documentation/networking/bonding.txt> for more
75 To compile this driver as a module, choose M here: the module
76 will be called bonding.
79 tristate "MAC-VLAN support (EXPERIMENTAL)"
80 depends on EXPERIMENTAL
82 This allows one to create virtual interfaces that map packets to
83 or from specific MAC addresses to a particular interface.
85 Macvlan devices can be added using the "ip" command from the
86 iproute2 package starting with the iproute2-2.6.23 release:
88 "ip link add link <real dev> [ address MAC ] [ NAME ] type macvlan"
90 To compile this driver as a module, choose M here: the module
91 will be called macvlan.
94 tristate "MAC-VLAN based tap driver (EXPERIMENTAL)"
97 This adds a specialized tap character device driver that is based
98 on the MAC-VLAN network interface, called macvtap. A macvtap device
99 can be added in the same way as a macvlan device, using 'type
100 macvlan', and then be accessed through the tap user space interface.
102 To compile this driver as a module, choose M here: the module
103 will be called macvtap.
106 tristate "EQL (serial line load balancing) support"
108 If you have two serial connections to some other computer (this
109 usually requires two modems and two telephone lines) and you use
110 SLIP (the protocol for sending Internet traffic over telephone
111 lines) or PPP (a better SLIP) on them, you can make them behave like
112 one double speed connection using this driver. Naturally, this has
113 to be supported at the other end as well, either with a similar EQL
114 Linux driver or with a Livingston Portmaster 2e.
116 Say Y if you want this and read
117 <file:Documentation/networking/eql.txt>. You may also want to read
118 section 6.2 of the NET-3-HOWTO, available from
119 <http://www.tldp.org/docs.html#howto>.
121 To compile this driver as a module, choose M here: the module
122 will be called eql. If unsure, say N.
125 tristate "Universal TUN/TAP device driver support"
128 TUN/TAP provides packet reception and transmission for user space
129 programs. It can be viewed as a simple Point-to-Point or Ethernet
130 device, which instead of receiving packets from a physical media,
131 receives them from user space program and instead of sending packets
132 via physical media writes them to the user space program.
134 When a program opens /dev/net/tun, driver creates and registers
135 corresponding net device tunX or tapX. After a program closed above
136 devices, driver will automatically delete tunXX or tapXX device and
137 all routes corresponding to it.
139 Please read <file:Documentation/networking/tuntap.txt> for more

150 This device is a local ethernet tunnel. Devices are created in pairs.
151 When one end receives the packet it appears on its pair and vice
155 tristate "General Instruments Surfboard 1000"
158 This is a driver for the General Instrument (also known as
159 NextLevel) SURFboard 1000 internal
160 cable modem. This is an ISA card which is used by a number of cable
161 TV companies to provide cable modem access. It's a one-way
162 downstream-only cable modem, meaning that your upstream net link is
163 provided by your regular phone modem.
165 At present this driver only compiles as a module, so say M here if
166 you have this card. The module will be called sb1000. Then read
167 <file:Documentation/networking/README.sb1000> for information on how
168 to use this module, as it needs special ppp scripts for establishing
169 a connection. Further documentation and the necessary scripts can be

181 tristate "Generic Media Independent Interface device support"
183 Most ethernet controllers have MII transceiver either as an external
184 or internal device. It is safe to say Y or M here even if your
185 ethernet card lacks MII.

196 bool "Ethernet (10 or 100Mbit)"
199 Ethernet (also called IEEE 802.3 or ISO 8802-2) is the most common
200 type of Local Area Network (LAN) in universities and companies.
202 Common varieties of Ethernet are: 10BASE-2 or Thinnet (10 Mbps over
203 coaxial cable, linking computers in a chain), 10BASE-T or twisted
204 pair (10 Mbps over twisted pair cable, linking computers to central
205 hubs), 10BASE-F (10 Mbps over optical fiber links, using hubs),
206 100BASE-TX (100 Mbps over two twisted pair cables, using hubs),
207 100BASE-T4 (100 Mbps over 4 standard voice-grade twisted pair
208 cables, using hubs), 100BASE-FX (100 Mbps over optical fiber links)
209 [the 100BASE varieties are also known as Fast Ethernet], and Gigabit
210 Ethernet (1 Gbps over optical fiber or short copper links).
212 If your Linux machine will be connected to an Ethernet and you have
213 an Ethernet network interface card (NIC) installed in your computer,
214 say Y here and read the Ethernet-HOWTO, available from
215 <http://www.tldp.org/docs.html#howto>. You will then also have
216 to say Y to the driver for your particular NIC.
218 Note that the answer to this question won't directly affect the
219 kernel: saying N will just cause the configurator to skip all
220 the questions about Ethernet network cards. If unsure, say N.
225 bool "EISA, VLB, PCI and on board controllers"
226 depends on ISA || EISA || PCI
228 This is another class of network cards which attach directly to the
229 bus. If you have one of those, say Y and read the Ethernet-HOWTO,
230 available from <http://www.tldp.org/docs.html#howto>.
232 Note that the answer to this question doesn't directly affect the
233 kernel: saying N will just cause the configurator to skip all
234 the questions about this class of network cards. If you say Y, you
235 will be asked for your specific card in the following questions. If
236 you are unsure, say Y.
239 bool "Pocket and portable adapters"
242 Cute little network (Ethernet) devices which attach to the parallel
243 port ("pocket adapters"), commonly used with laptops. If you have
244 one of those, say Y and read the Ethernet-HOWTO, available from
245 <http://www.tldp.org/docs.html#howto>.
247 If you want to plug a network (or some other) card into the PCMCIA
248 (or PC-card) slot of your laptop instead (PCMCIA is the standard for
249 credit card size extension cards used by all modern laptops), you
250 need the pcmcia-cs package (location contained in the file
251 <file:Documentation/Changes>) and you can say N here.
253 Laptop users should read the Linux Laptop home page at
254 <http://www.linux-on-laptops.com/> or
255 Tuxmobil - Linux on Mobile Computers at <http://www.tuxmobil.org/>.
257 Note that the answer to this question doesn't directly affect the
258 kernel: saying N will just cause the configurator to skip all
259 the questions about this class of network devices. If you say Y, you
260 will be asked for your specific device in the following questions.

273 Ethernet (also called IEEE 802.3 or ISO 8802-2) is the most common
274 type of Local Area Network (LAN) in universities and companies.
276 Say Y here to get to see options for Gigabit Ethernet drivers.
277 This option alone does not add any kernel code.
278 Note that drivers supporting both 100 and 1000 MBit may be listed
279 under "Ethernet (10 or 100MBit)" instead.
281 If you say N, all options in this submenu will be skipped and disabled.

337 This driver provides support for Xen paravirtual network
338 devices exported by a Xen network driver domain (often
341 The corresponding Linux backend driver is enabled by the
342 CONFIG_XEN_NETDEV_BACKEND option.
344 If you are compiling a kernel for use as Xen guest, you
345 should say Y here. To compile this driver as a module, chose
346 M here: the module will be called xen-netfront.
348 config XEN_NETDEV_BACKEND
349 tristate "Xen backend network device"
350 depends on XEN_BACKEND
352 This driver allows the kernel to act as a Xen network driver
353 domain which exports paravirtual network devices to other
354 Xen domains. These devices can be accessed by any operating
355 system that implements a compatible front end.
357 The corresponding Linux frontend driver is enabled by the
358 CONFIG_XEN_NETDEV_FRONTEND configuration option.
360 The backend driver presents a standard network device
361 endpoint for each paravirtual network device to the driver
362 domain network stack. These can then be bridged or routed
363 etc in order to provide full network connectivity.
365 If you are compiling a kernel to run in a Xen network driver
366 domain (often this is domain 0) you should say Y here. To
367 compile this driver as a module, chose M here: the module
368 will be called xen-netback.

385 tristate "FDDI driver support"
386 depends on (PCI || EISA || TC)
388 Fiber Distributed Data Interface is a high speed local area network
389 design; essentially a replacement for high speed Ethernet. FDDI can
390 run over copper or fiber. If you are connected to such a network and
391 want a driver for the FDDI card in your computer, say Y here (and
392 then also Y to the driver for your FDDI card, below). Most people
396 tristate "Digital DEFTA/DEFEA/DEFPA adapter support"
397 depends on FDDI && (PCI || EISA || TC)
399 This is support for the DIGITAL series of TURBOchannel (DEFTA),
400 EISA (DEFEA) and PCI (DEFPA) controllers which can connect you
401 to a local FDDI network.
403 To compile this driver as a module, choose M here: the module
404 will be called defxx. If unsure, say N.
408 prompt "Use MMIO instead of PIO" if PCI || EISA
410 default n if PCI || EISA
413 This instructs the driver to use EISA or PCI memory-mapped I/O
414 (MMIO) as appropriate instead of programmed I/O ports (PIO).
415 Enabling this gives an improvement in processing time in parts
416 of the driver, but it may cause problems with EISA (DEFEA)
417 adapters. TURBOchannel does not have the concept of I/O ports,
418 so MMIO is always used for these (DEFTA) adapters.
423 tristate "SysKonnect FDDI PCI support"
424 depends on FDDI && PCI
427 Say Y here if you have a SysKonnect FDDI PCI adapter.
428 The following adapters are supported by this driver:
429 - SK-5521 (SK-NET FDDI-UP)
430 - SK-5522 (SK-NET FDDI-UP DAS)
431 - SK-5541 (SK-NET FDDI-FP)

455 bool "HIPPI driver support (EXPERIMENTAL)"
456 depends on EXPERIMENTAL && INET && PCI
458 HIgh Performance Parallel Interface (HIPPI) is a 800Mbit/sec and
459 1600Mbit/sec dual-simplex switched or point-to-point network. HIPPI
460 can run over copper (25m) or fiber (300m on multi-mode or 10km on
461 single-mode). HIPPI networks are commonly used for clusters and to
462 connect to super computers. If you are connected to a HIPPI network
463 and have a HIPPI network card in your computer that you want to use
464 under Linux, say Y here (you must also remember to enable the driver
465 for your HIPPI card below). Most people will say N here.
468 tristate "Essential RoadRunner HIPPI PCI adapter support (EXPERIMENTAL)"
469 depends on HIPPI && PCI
471 Say Y here if this is your PCI HIPPI network card.
473 To compile this driver as a module, choose M here: the module
474 will be called rrunner. If unsure, say N.
476 config ROADRUNNER_LARGE_RINGS
477 bool "Use large TX/RX rings (EXPERIMENTAL)"
478 depends on ROADRUNNER
480 If you say Y here, the RoadRunner driver will preallocate up to 2 MB
481 of additional memory to allow for fastest operation, both for
482 transmitting and receiving. This memory cannot be used by any other
483 kernel code or by user space programs. Say Y here only if you have
487 tristate "PLIP (parallel port) support"
490 PLIP (Parallel Line Internet Protocol) is used to create a
491 reasonably fast mini network consisting of two (or, rarely, more)
492 local machines. A PLIP link from a Linux box is a popular means to
493 install a Linux distribution on a machine which doesn't have a
494 CD-ROM drive (a minimal system has to be transferred with floppies
495 first). The kernels on both machines need to have this PLIP option
496 enabled for this to work.
498 The PLIP driver has two modes, mode 0 and mode 1. The parallel
499 ports (the connectors at the computers with 25 holes) are connected
500 with "null printer" or "Turbo Laplink" cables which can transmit 4
501 bits at a time (mode 0) or with special PLIP cables, to be used on
502 bidirectional parallel ports only, which can transmit 8 bits at a
503 time (mode 1); you can find the wiring of these cables in
504 <file:Documentation/networking/PLIP.txt>. The cables can be up to
505 15m long. Mode 0 works also if one of the machines runs DOS/Windows
506 and has some PLIP software installed, e.g. the Crynwr PLIP packet
507 driver (<http://oak.oakland.edu/simtel.net/msdos/pktdrvr-pre.html>)
508 and winsock or NCSA's telnet.
510 If you want to use PLIP, say Y and read the PLIP mini-HOWTO as well
511 as the NET-3-HOWTO, both available from
512 <http://www.tldp.org/docs.html#howto>. Note that the PLIP
513 protocol has been changed and this PLIP driver won't work together
514 with the PLIP support in Linux versions 1.0.x. This option enlarges
515 your kernel by about 8 KB.
517 To compile this driver as a module, choose M here. The module
518 will be called plip. If unsure, say Y or M, in case you buy
522 tristate "PPP (point-to-point protocol) support"
525 PPP (Point to Point Protocol) is a newer and better SLIP. It serves
526 the same purpose: sending Internet traffic over telephone (and other
527 serial) lines. Ask your access provider if they support it, because
528 otherwise you can't use it; most Internet access providers these
529 days support PPP rather than SLIP.
531 To use PPP, you need an additional program called pppd as described
532 in the PPP-HOWTO, available at
533 <http://www.tldp.org/docs.html#howto>. Make sure that you have
534 the version of pppd recommended in <file:Documentation/Changes>.
535 The PPP option enlarges your kernel by about 16 KB.
537 There are actually two versions of PPP: the traditional PPP for
538 asynchronous lines, such as regular analog phone lines, and
539 synchronous PPP which can be used over digital ISDN lines for
540 example. If you want to use PPP over phone lines or other
541 asynchronous serial lines, you need to say Y (or M) here and also to
542 the next option, "PPP support for async serial ports". For PPP over
543 synchronous lines, you should say Y (or M) here and to "Support
544 synchronous PPP", below.
546 If you said Y to "Version information on all symbols" above, then
547 you cannot compile the PPP driver into the kernel; you can then only
548 compile it as a module. To compile this driver as a module, choose M
549 here. The module will be called ppp_generic.
552 bool "PPP multilink support (EXPERIMENTAL)"
553 depends on PPP && EXPERIMENTAL
555 PPP multilink is a protocol (defined in RFC 1990) which allows you
556 to combine several (logical or physical) lines into one logical PPP
557 connection, so that you can utilize your full bandwidth.
559 This has to be supported at the other end as well and you need a
560 version of the pppd daemon which understands the multilink protocol.
568 Say Y here if you want to be able to filter the packets passing over
569 PPP interfaces. This allows you to control which packets count as
570 activity (i.e. which packets will reset the idle timer or bring up
571 a demand-dialed link) and which packets are to be dropped entirely.
572 You need to say Y here if you wish to use the pass-filter and
573 active-filter options to pppd.
578 tristate "PPP support for async serial ports"
582 Say Y (or M) here if you want to be able to use PPP over standard
583 asynchronous serial ports, such as COM1 or COM2 on a PC. If you use
584 a modem (not a synchronous or ISDN modem) to contact your ISP, you
587 To compile this driver as a module, choose M here.
592 tristate "PPP support for sync tty ports"
595 Say Y (or M) here if you want to be able to use PPP over synchronous
596 (HDLC) tty devices, such as the SyncLink adapter. These devices
597 are often used for high-speed leased lines like T1/E1.
599 To compile this driver as a module, choose M here.
602 tristate "PPP Deflate compression"
607 Support for the Deflate compression method for PPP, which uses the
608 Deflate algorithm (the same algorithm that gzip uses) to compress
609 each PPP packet before it is sent over the wire. The machine at the
610 other end of the PPP link (usually your ISP) has to support the
611 Deflate compression method as well for this to be useful. Even if
612 they don't support it, it is safe to say Y here.
614 To compile this driver as a module, choose M here.
617 tristate "PPP BSD-Compress compression"
620 Support for the BSD-Compress compression method for PPP, which uses
621 the LZW compression method to compress each PPP packet before it is
622 sent over the wire. The machine at the other end of the PPP link
623 (usually your ISP) has to support the BSD-Compress compression
624 method as well for this to be useful. Even if they don't support it,
625 it is safe to say Y here.
627 The PPP Deflate compression method ("PPP Deflate compression",
628 above) is preferable to BSD-Compress, because it compresses better
631 Note that the BSD compression code will always be compiled as a
632 module; it is called bsd_comp and will show up in the directory
633 modules once you have said "make modules". If unsure, say N.
636 tristate "PPP MPPE compression (encryption) (EXPERIMENTAL)"
637 depends on PPP && EXPERIMENTAL
643 Support for the MPPE Encryption protocol, as employed by the
644 Microsoft Point-to-Point Tunneling Protocol.
646 See http://pptpclient.sourceforge.net/ for information on
647 configuring PPTP clients and servers to utilize this method.
650 tristate "PPP over Ethernet (EXPERIMENTAL)"
651 depends on EXPERIMENTAL && PPP
653 Support for PPP over Ethernet.
655 This driver requires the latest version of pppd from the CVS
656 repository at cvs.samba.org. Alternatively, see the
657 RoaringPenguin package (<http://www.roaringpenguin.com/pppoe>)
658 which contains instruction on how to use this driver (under
659 the heading "Kernel mode PPPoE").
662 tristate "PPP over IPv4 (PPTP) (EXPERIMENTAL)"
663 depends on EXPERIMENTAL && PPP && NET_IPGRE_DEMUX
665 Support for PPP over IPv4.(Point-to-Point Tunneling Protocol)
667 This driver requires pppd plugin to work in client mode or
668 modified pptpd (poptop) to work in server mode.

674 depends on ATM && PPP
676 Support PPP (Point to Point Protocol) encapsulated in ATM frames.
677 This implementation does not yet comply with section 8 of RFC2364,
678 which can lead to bad results if the ATM peer loses state and
679 changes its encapsulation unilaterally.
682 tristate "PPP over L2TP (EXPERIMENTAL)"
683 depends on EXPERIMENTAL && L2TP && PPP
685 Support for PPP-over-L2TP socket family. L2TP is a protocol
686 used by ISPs and enterprises to tunnel PPP traffic over UDP
687 tunnels. L2TP is replacing PPTP for VPN uses.
690 tristate "SLIP (serial line) support"
692 Say Y if you intend to use SLIP or CSLIP (compressed SLIP) to
693 connect to your Internet service provider or to connect to some
694 other local Unix box or if you want to configure your Linux box as a
695 Slip/CSlip server for other people to dial in. SLIP (Serial Line
696 Internet Protocol) is a protocol used to send Internet traffic over
697 serial connections such as telephone lines or null modem cables;
698 nowadays, the protocol PPP is more commonly used for this same
701 Normally, your access provider has to support SLIP in order for you
702 to be able to use it, but there is now a SLIP emulator called SLiRP
703 around (available from
704 <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
705 allows you to use SLIP over a regular dial up shell connection. If
706 you plan to use SLiRP, make sure to say Y to CSLIP, below. The
707 NET-3-HOWTO, available from
708 <http://www.tldp.org/docs.html#howto>, explains how to
709 configure SLIP. Note that you don't need this option if you just
710 want to run term (term is a program which gives you almost full
711 Internet connectivity if you have a regular dial up shell account on
712 some Internet connected Unix computer. Read
713 <http://www.bart.nl/~patrickr/term-howto/Term-HOWTO.html>). SLIP
714 support will enlarge your kernel by about 4 KB. If unsure, say N.
716 To compile this driver as a module, choose M here. The module
719 config SLIP_COMPRESSED
720 bool "CSLIP compressed headers"
724 This protocol is faster than SLIP because it uses compression on the
725 TCP/IP headers (not on the data itself), but it has to be supported
726 on both ends. Ask your access provider if you are not sure and
727 answer Y, just in case. You will still be able to use plain SLIP. If
728 you plan to use SLiRP, the SLIP emulator (available from
729 <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
730 allows you to use SLIP over a regular dial up shell connection, you
731 definitely want to say Y here. The NET-3-HOWTO, available from
732 <http://www.tldp.org/docs.html#howto>, explains how to configure
733 CSLIP. This won't enlarge your kernel.
738 This option enables Van Jacobsen serial line header compression
742 bool "Keepalive and linefill"
745 Adds additional capabilities to the SLIP driver to support the
746 RELCOM line fill and keepalive monitoring. Ideal on poor quality
749 config SLIP_MODE_SLIP6
750 bool "Six bit SLIP encapsulation"
753 Just occasionally you may need to run IP over hostile serial
754 networks that don't pass all control characters or are only seven
755 bit. Saying Y here adds an extra mode you can use with SLIP:
756 "slip6". In this mode, SLIP will only send normal ASCII symbols over
757 the serial device. Naturally, this has to be supported at the other
758 end of the link as well. It's good enough, for example, to run IP
759 over the async ports of a Camtec JNT Pad. If unsure, say N.
762 bool "Fibre Channel driver support"
763 depends on SCSI && PCI
765 Fibre Channel is a high speed serial protocol mainly used to connect
766 large storage devices to the computer; it is compatible with and
767 intended to replace SCSI.
769 If you intend to use Fibre Channel, you need to have a Fibre channel
770 adaptor card in your computer; say Y here and to the driver for your
771 adaptor below. You also should have said Y to "SCSI support" and
772 "SCSI generic support".
775 tristate "Network console logging support"
777 If you want to log kernel messages over the network, enable this.
778 See <file:Documentation/networking/netconsole.txt> for details.
780 config NETCONSOLE_DYNAMIC
781 bool "Dynamic reconfiguration of logging targets"
782 depends on NETCONSOLE && SYSFS && CONFIGFS_FS && \
783 !(NETCONSOLE=y && CONFIGFS_FS=m)
785 This option enables the ability to dynamically reconfigure target
786 parameters (interface, IP addresses, port numbers, MAC addresses)
787 at runtime through a userspace interface exported using configfs.
788 See <file:Documentation/networking/netconsole.txt> for details.
794 bool "Netpoll traffic trapping"
798 config NET_POLL_CONTROLLER
802 tristate "Virtio network driver (EXPERIMENTAL)"
803 depends on EXPERIMENTAL && VIRTIO
805 This is the virtual network driver for virtio. It can be used with
806 lguest or QEMU based VMMs (like KVM or Xen). Say Y or M.
809 tristate "VMware VMXNET3 ethernet driver"
810 depends on PCI && INET
812 This driver supports VMware's vmxnet3 virtual ethernet NIC.
813 To compile this driver as a module, choose M here: the
814 module will be called vmxnet3.
