The Tigon contains an embedded R4000 CPU, gigabit MAC, dual DMA channels and a PCI interface unit. 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. The Tigon I and II support hardware multicast address filtering, VLAN tag extraction and insertion, and jumbo .Tn Ethernet frames sizes up to 9000 bytes. Note that the Tigon I chipset is no longer in active production: all new adapters should come equipped with Tigon II chipsets. .Pp There are several PCI boards available from both Alteon and other vendors that use the Tigon chipset under OEM contract. The .Nm driver has been tested with the following Tigon-based adapters: .Bl -bullet -offset indent .It The Alteon AceNIC V gigabit (1000BASE-SX and 1000BASE-T variants) .Tn Ethernet adapter .It The 3Com 3c985-SX gigabit .Tn Ethernet adapter .It The Netgear GA620 gigabit (1000BASE-SX and 1000BASE-T variants) .Tn Ethernet adapter .It The Digital EtherWORKS 1000SX PCI Gigabit Adapter (DEGPA) .El .Pp The following should also be supported but have not yet been tested: .Bl -bullet -offset indent .It Silicon Graphics PCI gigabit .Tn Ethernet adapter .El .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: .Pp .Bl -tag -width xxxxxxxxxxxxxxxxxxxx .It autoselect Enable autoselection of the media type and options. .It 10baseT/UTP 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 .Tn 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 .Tn Ethernet over multimode fiber ) operation. Only full .Ar full-duplex mode is supported at this speed. .It 1000baseT Set 1000Mbps (gigabit .Tn Ethernet over twisted pair ) operation. Only full .Ar full-duplex mode is supported at this speed. .El .Pp The .Nm driver supports the following media options: .Pp .Bl -tag -width xxxxxxxxxxxxxxxxxxxx .It full-duplex Force full duplex operation. .It half-duplex Force half duplex operation. .El .Pp The Alteon Tigon and Tigon II support IPv4/TCP/UDP checksumming in hardware. The .Nm supports this feature of the chip's firmware. See .Xr ifconfig 8 for information on how to enable this feature. .Pp For more information on configuring this device, see .Xr ifconfig 8 . .Sh DIAGNOSTICS .Bl -diag .It "ti%d: can't map memory space" A fatal initialization error has occurred. .It "ti%d: couldn't map / establish interrupt" A fatal initialization error has occurred. .It "ti%d: jumbo buffer allocation failed" 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 netintro 4 , .Xr pci 4 , .Xr ifconfig 8 .Sh HISTORY The .Nm device driver first appeared in .Nx 1.4.2 . .Sh AUTHORS The .Nm driver was written by .An Bill Paul Aq wpaul@ctr.columbia.edu . .Sh BUGS The driver currently tries to access some on-board memory transparently. This mapping (BUS_SPACE_MAP_LINEAR) fails on systems where the corresponding PCI memory range is located in "sparse" space only. .Pp This driver currently does not work on big-endian systems.
