67 driver provides support for Adaptec Duralink Fast Ethernet adapters
68 based on the Adaptec AIC-6915 "Starfire" chipset.
70 The AIC-6915 is a bus master controller with an MII interface.
72 supports high and low priority transmit and receive queues, TCP/IP
73 checksum offload, multiple DMA descriptor formats and both polling
74 and producer/consumer DMA models.
75 The AIC-6915 receive filtering
76 options include a 16 entry perfect filter, a 512-bit hash table
77 for multicast addresses, a 512-bit hash table for priority address
78 matching and VLAN filtering.
79 An external MII-compliant transceiver
80 is required for media interfacing.
82 Multiport adapters consist of several AIC-6915 controllers connected
83 via a PCI to PCI bridge.
84 Each controller is treated as a separate
91 driver supports the following media types:
92 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
94 Enable autoselection of the media type and options.
95 The user can manually override
96 the autoselected mode by adding media options to the
100 Set 10Mbps operation.
103 option can also be used to select either
109 Set 100Mbps (Fast Ethernet) operation.
112 option can also be used to select either
121 driver supports the following media options:
122 .Bl -tag -width xxxxxxxxxxxxxxxxxxxx
124 Force full duplex operation
126 Force half duplex operation.

138 ANA-62011 64-bit single port 10/100baseTX adapter
140 ANA-62022 64-bit dual port 10/100baseTX adapter
142 ANA-62044 64-bit quad port 10/100baseTX adapter
144 ANA-69011 32-bit single port 10/100baseTX adapter

158 The accepted range is 0 to 31, the default value is 1 (102.4us).
159 Value 0 completely disables the interrupt moderation.
160 The interface does not need to be brought down and up again before
161 a change takes effect.
162 .It Va dev.sf.%d.stats
163 Display lots of useful MAC counters maintained in the driver.

168 A fatal initialization error has occurred.
170 happen if the PCI BIOS not configured the device, which may be because
171 the BIOS has been configured for a "Plug and Play" operating system.
172 The "Plug and Play OS" setting in the BIOS should be set to "no" or

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