device 41.Sh SYNOPSIS 42.Cd "ti* at pci?" 43.Cd "ti* at sbus?" 44.Sh DESCRIPTION 45The 46.Nm 47driver provides support for Gigabit Ethernet adapters based on the 48Alteon Networks Tigon Gigabit Ethernet controller chip, including 49the following: 50.Pp 51.Bl -bullet -compact -offset indent 52.It 533Com 3C985-SX Gigabit Ethernet (1000baseSX) 54.It 553Com 3C985B-SX Gigabit Ethernet (1000baseSX) 56.It 57Alteon AceNIC V Gigabit Ethernet (1000baseSX) 58.It 59Alteon AceNIC V Gigabit Ethernet (1000baseT) 60.It 61Digital EtherWORKS 1000SX PCI Gigabit Ethernet (1000baseSX) 62.It 63Farallon PN9000SX Gigabit Ethernet (1000baseSX) 64.It 65Netgear GA620 Gigabit Ethernet (1000baseSX) 66.It 67Netgear GA620T Gigabit Ethernet (1000baseT) 68.It 69Silicon Graphics Gigabit Ethernet (1000baseSX) 70.It 71Silicon Graphics Gigabit Ethernet (1000baseT) 72.It 73Sun Vector Gigabit Ethernet (1000baseSX) 74.El 75.Pp 76The Tigon contains an embedded R4000 CPU, Gigabit MAC, dual DMA channels and 77a PCI interface unit. 78The Tigon II contains two R4000 CPUs and other refinements. 79Either chip can be used in either a 32-bit or 64-bit PCI slot. 80Communication with the chip is achieved via PCI shared memory and 81bus master DMA. 82SBus cards are also available and use a special bridge chip. 83The Tigon I and II support hardware multicast address filtering, 84VLAN tag insertion and stripping, and jumbo frames. 85.Pp 86While the Tigon chipset supports 10, 100 and 1000Mbps speeds, support for 8710 and 100Mbps speeds is only available on boards with the proper 88transceivers. 89Most adapters are only designed to work at 1000Mbps, however the driver 90should support those NICs that work at lower speeds as well. 91.Pp 92The 93.Nm 94driver supports the following media types: 95.Bl -tag -width full-duplex 96.It autoselect 97Enable autoselection of the media type and options. 98The user can manually override 99the autoselected mode by adding media options to the appropriate 100.Xr hostname.if 5 101file. 102.It 10baseT 103Set 10Mbps operation 104The 105.Ar mediaopt 106option can also be used to select either 107.Ar full-duplex 108or 109.Ar half-duplex 110modes. 111.It 100baseTX 112Set 100Mbps (Fast Ethernet) operation. 113The 114.Ar mediaopt 115option can also be used to select either 116.Ar full-duplex 117or 118.Ar half-duplex 119modes. 120.It 1000baseSX 121Set 1000Mbps (Gigabit Ethernet) on fiber operation. 122Only 123.Ar full-duplex 124mode is supported at this speed. 125.It 1000baseT 126Set 1000Mbps (Gigabit Ethernet) on copper operation. 127.El 128.Pp 129The 130.Nm 131driver supports the following media options: 132.Bl -tag -width full-duplex 133.It full-duplex 134Force full duplex operation 135.It half-duplex 136Force half duplex operation 137.El 138.Pp 139For more information on configuring this device, see 140.Xr ifconfig 8 . 141.Sh FILES 142Two firmware files are necessary, for Tigon 1 and Tigon 2 devices. 143These are loaded on demand 144when the device is attached: 145.Pp 146.Bl -tag -width Ds -offset indent -compact 147.It Pa /etc/firmware/tigon1 148.It Pa /etc/firmware/tigon2 149.El 150.Sh DIAGNOSTICS 151.Bl -diag 152.It "ti0: couldn't map memory" 153A fatal initialization error has occurred. 154.It "ti0: couldn't map interrupt" 155A fatal initialization error has occurred. 156.It "ti0: no memory for softc struct!" 157The driver failed to allocate memory for per-device instance information 158during initialization. 159.It "ti0: failed to enable memory mapping!" 160The driver failed to initialize PCI shared memory mapping. 161This might happen if the card is not in a bus-master slot. 162.It "ti0: no memory for jumbo buffers!" 163The driver failed to allocate memory for jumbo frames during 164initialization. 165.It "ti0: bios thinks we're in a 64 bit slot, but we aren't" 166The BIOS has programmed the NIC as though it had been installed in 167a 64-bit PCI slot, but in fact the NIC is in a 32-bit slot. 168This happens as a result of a bug in some BIOSes. 169This can be worked around on the Tigon II, but 170on the Tigon I initialization will fail. 171.It "ti0: board self-diagnostics failed!" 172The ROMFAIL bit in the CPU state register was set after system 173startup, indicating that the on-board NIC diagnostics failed. 174.It "ti0: unknown hwrev" 175The driver detected a board with an unsupported hardware revision. 176The 177.Nm 178driver supports revision 4 (Tigon 1) and revision 6 (Tigon 2) chips 179and has firmware only for those devices. 180.It "ti0: watchdog timeout -- resetting" 181The device has stopped responding to the network, or there is a problem with 182the network connection (cable). 183.El 184.Sh SEE ALSO 185.Xr arp 4 , 186.Xr ifmedia 4
