38 .Nd "Adaptec AIC-6915"
40 PCI Fast Ethernet adapter driver
42 To compile this driver into the kernel,
43 place the following lines in your
44 kernel configuration file:
45 .Bd -ragged -offset indent
50 Alternatively, to load the driver as a
51 module at boot time, place the following line in
53 .Bd -literal -offset indent
59 driver provides support for Adaptec Duralink Fast Ethernet adapters
60 based on the Adaptec AIC-6915 "Starfire" chipset.
62 The AIC-6915 is a bus master controller with an MII interface.
64 supports high and low priority transmit and receive queues, TCP/IP
65 checksum offload, multiple DMA descriptor formats and both polling
66 and producer/consumer DMA models.
67 The AIC-6915 receive filtering
68 options include a 16 entry perfect filter, a 512-bit hash table
69 for multicast addresses, a 512-bit hash table for priority address
70 matching and VLAN filtering.
71 An external MII-compliant transceiver
72 is required for media interfacing.
74 Multiport adapters consist of several AIC-6915 controllers connected
75 via a PCI to PCI bridge.
76 Each controller is treated as a separate
83 driver supports the following media types:
85 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
87 Enable autoselection of the media type and options.
88 The user can manually override
89 the autoselected mode by adding media options to the
96 option can also be used to select either
102 Set 100Mbps (Fast Ethernet) operation.
105 option can also be used to select either
114 driver supports the following media options:
116 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
118 Force full duplex operation
120 Force half duplex operation.

126 Adapters supported by the
132 ANA-62011 64-bit single port 10/100baseTX adapter
134 ANA-62022 64-bit dual port 10/100baseTX adapter
136 ANA-62044 64-bit quad port 10/100baseTX adapter
138 ANA-69011 32-bit single port 10/100baseTX adapter
140 ANA-62020 64-bit single port 100baseFX adapter
143 The following variables are available as both
148 .Bl -tag -width indent
149 .It Va dev.sf.%d.int_mod
150 Maximum amount of time to delay interrupt processing in units of
152 The accepted range is 0 to 31, the default value is 1 (102.4us).
153 Value 0 completely disables the interrupt moderation.
154 The interface does not need to be brought down and up again before
155 a change takes effect.
156 .It Va dev.sf.%d.stats
157 Display lots of useful MAC counters maintained in the driver.
161 .It "sf%d: couldn't map memory"
162 A fatal initialization error has occurred.
164 happen if the PCI BIOS not configured the device, which may be because
165 the BIOS has been configured for a "Plug and Play" operating system.
166 The "Plug and Play OS" setting in the BIOS should be set to "no" or
167 "off" in order for PCI devices to work properly with

174 The "Plug and Play OS" setting in the BIOS should be set to "no" or

177 .It "sf%d: couldn't map interrupt"
178 A fatal initialization error has occurred.
179 .It "sf%d: no memory for softc struct!"
180 The driver failed to allocate memory for per-device instance information
181 during initialization.
182 .It "sf%d: failed to enable I/O ports/memory mapping!"
183 The driver failed to initialize PCI I/O port or shared memory access.
184 This might happen if the card is not in a bus-master slot.
185 .It "sf%d: watchdog timeout"
186 The device has stopped responding to the network, or there is a problem with
187 the network connection (cable).
