41 PCI fast ethernet adapter driver
48 driver provides support for Adaptec Duralink fast ethernet adapters
49 based on the Adaptec AIC-6915 "Starfire" chipset.
53 .Bl -bullet -compact -offset indent
55 ANA-62011 64-bit single port 10/100baseTX adapter
57 ANA-62022 64-bit dual port 10/100baseTX adapter
59 ANA-62044 64-bit quad port 10/100baseTX adapter
61 ANA-69011 32-bit single port 10/100baseTX adapter
63 ANA-62020 64-bit single port 100baseFX adapter
66 The AIC-6915 is a bus master controller with an MII interface.
68 supports high and low priority transmit and receive queues, TCP/IP
69 checksum offload, multiple DMA descriptor formats and both polling
70 and producer/consumer DMA models.
71 The AIC-6915 receive filtering
72 options include a 16 entry perfect filter, a 512-bit hash table
73 for multicast addresses, a 512-bit hash table for priority address
74 matching and VLAN filtering.
75 An external MII-compliant transceiver
76 is required for media interfacing.
78 Multiport adapters consist of several AIC-6915 controllers connected
79 via a PCI to PCI bridge.
80 Each controller is treated as a separate
87 driver supports the following media types:
88 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
90 Enable autoselection of the media type and options.
91 The user can manually override
92 the autoselected mode by adding media options to the
99 option can also be used to select either
105 Set 100Mbps (fast ethernet) operation.
108 option can also be used to select either
117 driver supports the following media options:
118 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
120 Force full duplex operation
122 Force half duplex operation.

133 the BIOS has been configured for a "Plug and Play" operating system.
134 The "Plug and Play OS" setting int he BIOS should be set to "no" or

146 A fatal initialization error has occurred.
147 .It "sf%d: no memory for softc struct!"
148 The driver failed to allocate memory for per-device instance information
149 during initialization.
150 .It "sf%d: failed to enable I/O ports/memory mapping!"
151 The driver failed to initialize PCI I/O port or shared memory access.
152 This might happen if the card is not in a bus-master slot.
153 .It "sf%d: watchdog timeout"
154 The device has stopped responding to the network, or there is a problem with
155 the network connection (cable).
