32 .Nd Attansic/Atheros L1 Gigabit Ethernet driver
34 To compile this driver into the kernel,
35 place the following lines in your
36 kernel configuration file:
37 .Bd -ragged -offset indent
42 Alternatively, to load the driver as a
43 module at boot time, place the following line in
45 .Bd -literal -offset indent
51 device driver provides support for Attansic/Atheros L1 PCI Express
52 Gigabit Ethernet controllers.
54 All LOMs supported by the
56 driver have TCP/UDP/IP checksum offload for both transmit and receive,
57 hardware VLAN tag stripping/insertion features and
58 an interrupt moderation mechanism as well as
59 a 64-bit multicast hash filter.
61 The L1 also supports Jumbo Frames (up to 10240 bytes),
62 which can be configured via the interface MTU setting.
63 Selecting an MTU larger than 1500 bytes with the
65 utility configures the adapter to receive and transmit Jumbo Frames.
69 driver supports the following media types:
70 .Bl -tag -width ".Cm 10baseT/UTP"
72 Enable autoselection of the media type and options.
73 The user can manually override
74 the autoselected mode by adding media options to
79 Set 100Mbps (Fast Ethernet) operation.
81 Set 1000baseT operation over twisted pair.
86 driver supports the following media options:
87 .Bl -tag -width ".Cm full-duplex"
89 Force full duplex operation.
91 Force half duplex operation.
94 For more information on configuring this device, see
99 driver provides support for LOMs based on
100 Attansic/Atheros L1 Gigabit Ethernet controller chips, including:
139 The following variables are available as
142 .Bl -tag -width "xxxxxx"
143 .It Va dev.age%d.int_mod
144 Maximum amount of time to delay interrupt processing in units of 2us.
145 The accepted range is 0 to 65000, the default is 50 (100us).
146 Value 0 completely disables the interrupt moderation.
147 .It Va dev.age%d.stats
148 Display lots of useful MAC counters maintained in the driver.
162 driver was written by
164 .Aq yongari@FreeBSD.org .
