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:
84 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
86 Enable autoselection of the media type and options.
87 The user can manually override
88 the autoselected mode by adding media options to the
95 option can also be used to select either
101 Set 100Mbps (Fast Ethernet) operation.
104 option can also be used to select either
113 driver supports the following media options:
114 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
116 Force full duplex operation
118 Force half duplex operation.

130 ANA-62011 64-bit single port 10/100baseTX adapter
132 ANA-62022 64-bit dual port 10/100baseTX adapter
134 ANA-62044 64-bit quad port 10/100baseTX adapter
136 ANA-69011 32-bit single port 10/100baseTX adapter
138 ANA-62020 64-bit single port 100baseFX adapter
141 The following variables are available as both

147 .It Va dev.sf.%d.int_mod
148 Maximum amount of time to delay interrupt processing in units of
150 The accepted range is 0 to 31, the default value is 1 (102.4us).
151 Value 0 completely disables the interrupt moderation.
152 The interface does not need to be brought down and up again before
153 a change takes effect.
154 .It Va dev.sf.%d.stats
155 Display lots of useful MAC counters maintained in the driver.
159 .It "sf%d: couldn't map memory"
160 A fatal initialization error has occurred.
162 happen if the PCI BIOS not configured the device, which may be because
163 the BIOS has been configured for a "Plug and Play" operating system.
164 The "Plug and Play OS" setting in the BIOS should be set to "no" or
165 "off" in order for PCI devices to work properly with

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