The Tigon II contains two R4000 CPUs and other refinements. Either chip can be used in either a 32-bit or 64-bit PCI slot. Communication with the chip is achieved via PCI shared memory and bus master DMA. SBus cards are also available and use a special bridge chip. The Tigon I and II support hardware multicast address filtering, VLAN tag insertion and stripping, and Jumbo frame sizes up to 9000 bytes. .Pp While the Tigon chipset supports 10, 100 and 1000Mbps speeds, support for 10 and 100Mbps speeds is only available on boards with the proper transceivers. Most adapters are only designed to work at 1000Mbps, however the driver should support those NICs that work at lower speeds as well. .Pp Support for Jumbo frames is provided via the interface MTU setting. Selecting an MTU larger than 1500 bytes with the .Xr ifconfig 8 utility configures the adapter to receive and transmit Jumbo frames. Using Jumbo frames can greatly improve performance for certain tasks, such as file transfers and data streaming. .Pp The .Nm driver supports the following media types: .Bl -tag -width full-duplex .It autoselect Enable autoselection of the media type and options. The user can manually override the autoselected mode by adding media options to the appropriate .Xr hostname.if 5 file. .It 10baseT Set 10Mbps operation The .Ar mediaopt option can also be used to select either .Ar full-duplex or .Ar half-duplex modes. .It 100baseTX Set 100Mbps (Fast Ethernet) operation. The .Ar mediaopt option can also be used to select either .Ar full-duplex or .Ar half-duplex modes. .It 1000baseSX Set 1000Mbps (Gigabit Ethernet) on fiber operation. Only .Ar full-duplex mode is supported at this speed. .It 1000baseT Set 1000Mbps (Gigabit Ethernet) on copper operation. .El .Pp The .Nm driver supports the following media options: .Bl -tag -width full-duplex .It full-duplex Force full duplex operation .It half-duplex Force half duplex operation .El .Pp For more information on configuring this device, see .Xr ifconfig 8 . .Sh FILES Two firmware files are necessary, for Tigon 1 and Tigon 2 devices. These are loaded on demand when the device is attached: .Pp .Bl -tag -width Ds -offset indent -compact .It Pa /etc/firmware/tigon1 .It Pa /etc/firmware/tigon2 .El .Sh DIAGNOSTICS .Bl -diag .It "ti%d: couldn't map memory" A fatal initialization error has occurred. .It "ti%d: couldn't map interrupt" A fatal initialization error has occurred. .It "ti%d: no memory for softc struct!" The driver failed to allocate memory for per-device instance information during initialization. .It "ti%d: failed to enable memory mapping!" The driver failed to initialize PCI shared memory mapping. This might happen if the card is not in a bus-master slot. .It "ti%d: no memory for jumbo buffers!" The driver failed to allocate memory for Jumbo frames during initialization. .It "ti%d: bios thinks we're in a 64 bit slot, but we aren't" The BIOS has programmed the NIC as though it had been installed in a 64-bit PCI slot, but in fact the NIC is in a 32-bit slot. This happens as a result of a bug in some BIOSes. This can be worked around on the Tigon II, but on the Tigon I initialization will fail. .It "ti%d: board self-diagnostics failed!" The ROMFAIL bit in the CPU state register was set after system startup, indicating that the on-board NIC diagnostics failed. .It "ti%d: unknown hwrev" The driver detected a board with an unsupported hardware revision. The .Nm driver supports revision 4 (Tigon 1) and revision 6 (Tigon 2) chips and has firmware only for those devices. .It "ti%d: watchdog timeout" The device has stopped responding to the network, or there is a problem with the network connection (cable). .El .Sh SEE ALSO .Xr arp 4 , .Xr ifmedia 4 , .Xr intro 4 , .Xr netintro 4 , .Xr pci 4 , .Xr sbus 4 , .Xr hostname.if 5 , .Xr ifconfig 8 .Sh HISTORY The .Nm device driver first appeared in .Fx 3.0 . .Ox support first appeared in .Ox 2.6 .
