33.Dd January 21, 2008 34.Dt SF 4 35.Os 36.Sh NAME 37.Nm sf 38.Nd "Adaptec AIC-6915" 39.Qq Starfire 40PCI Fast Ethernet adapter driver 41.Sh SYNOPSIS 42To compile this driver into the kernel, 43place the following lines in your 44kernel configuration file: 45.Bd -ragged -offset indent 46.Cd "device miibus" 47.Cd "device sf" 48.Ed 49.Pp 50Alternatively, to load the driver as a 51module at boot time, place the following line in 52.Xr loader.conf 5 : 53.Bd -literal -offset indent 54if_sf_load="YES" 55.Ed 56.Sh DESCRIPTION 57The 58.Nm 59driver provides support for Adaptec Duralink Fast Ethernet adapters 60based on the Adaptec AIC-6915 "Starfire" chipset. 61.Pp 62The AIC-6915 is a bus master controller with an MII interface. 63It 64supports high and low priority transmit and receive queues, TCP/IP 65checksum offload, multiple DMA descriptor formats and both polling 66and producer/consumer DMA models. 67The AIC-6915 receive filtering 68options include a 16 entry perfect filter, a 512-bit hash table 69for multicast addresses, a 512-bit hash table for priority address 70matching and VLAN filtering. 71An external MII-compliant transceiver 72is required for media interfacing. 73.Pp 74Multiport adapters consist of several AIC-6915 controllers connected 75via a PCI to PCI bridge. 76Each controller is treated as a separate 77interface by the 78.Nm 79driver. 80.Pp 81The 82.Nm 83driver supports the following media types: 84.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 85.It autoselect 86Enable autoselection of the media type and options. 87The user can manually override 88the autoselected mode by adding media options to the 89.Pa /etc/rc.conf 90file. 91.It 10baseT/UTP 92Set 10Mbps operation. 93The 94.Ar mediaopt 95option can also be used to select either 96.Ar full-duplex 97or 98.Ar half-duplex 99modes. 100.It 100baseTX 101Set 100Mbps (Fast Ethernet) operation. 102The 103.Ar mediaopt 104option can also be used to select either 105.Ar full-duplex 106or 107.Ar half-duplex 108modes. 109.El 110.Pp 111The 112.Nm 113driver supports the following media options: 114.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 115.It full-duplex 116Force full duplex operation 117.It half-duplex 118Force half duplex operation. 119.El 120.Pp 121For more information on configuring this device, see 122.Xr ifconfig 8 . 123.Sh HARDWARE 124Adapters supported by the 125.Nm 126driver include: 127.Pp 128.Bl -bullet -compact 129.It 130ANA-62011 64-bit single port 10/100baseTX adapter 131.It 132ANA-62022 64-bit dual port 10/100baseTX adapter 133.It 134ANA-62044 64-bit quad port 10/100baseTX adapter 135.It 136ANA-69011 32-bit single port 10/100baseTX adapter 137.It 138ANA-62020 64-bit single port 100baseFX adapter 139.El 140.Sh SYSCTL VARIABLES 141The following variables are available as both 142.Xr sysctl 8 143variables and 144.Xr loader 8 145tunables: 146.Bl -tag -width indent 147.It Va dev.sf.%d.int_mod 148Maximum amount of time to delay interrupt processing in units of 149102.4us. 150The accepted range is 0 to 31, the default value is 1 (102.4us). 151Value 0 completely disables the interrupt moderation. 152The interface does not need to be brought down and up again before 153a change takes effect. 154.It Va dev.sf.%d.stats 155Display lots of useful MAC counters maintained in the driver. 156.El 157.Sh DIAGNOSTICS 158.Bl -diag 159.It "sf%d: couldn't map memory" 160A fatal initialization error has occurred. 161This may 162happen if the PCI BIOS not configured the device, which may be because 163the BIOS has been configured for a "Plug and Play" operating system. 164The "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 166.Fx . 167.It "sf%d: couldn't map ports" 168A fatal initialization error has occurred. 169This may 170happen if the PCI BIOS not configured the device, which may be because 171the BIOS has been configured for a "Plug and Play" operating system. 172The "Plug and Play OS" setting in the BIOS should be set to "no" or 173"off" in order for PCI devices to work properly with 174.Fx . 175.It "sf%d: couldn't map interrupt" 176A fatal initialization error has occurred. 177.It "sf%d: no memory for softc struct!" 178The driver failed to allocate memory for per-device instance information 179during initialization. 180.It "sf%d: failed to enable I/O ports/memory mapping!" 181The driver failed to initialize PCI I/O port or shared memory access. 182This might happen if the card is not in a bus-master slot. 183.It "sf%d: watchdog timeout" 184The device has stopped responding to the network, or there is a problem with 185the network connection (cable). 186.El 187.Sh SEE ALSO 188.Xr altq 4 , 189.Xr arp 4 , 190.Xr miibus 4 , 191.Xr netintro 4 ,
