33.Dd March 4, 1999 34.Dt TI 4 35.Os FreeBSD 36.Sh NAME 37.Nm ti 38.Nd 39Alteon Networks Tigon I and Tigon II gigabit ethernet driver 40.Sh SYNOPSIS 41.Cd "device ti" 42.Sh DESCRIPTION 43The 44.Nm 45driver provides support for PCI gigabit ethernet adapters based on 46the Alteon Networks Tigon gigabit ethernet controller chip. 47The Tigon 48contains an embedded R4000 CPU, gigabit MAC, dual DMA channels and 49a PCI interface unit. 50The Tigon II contains two R4000 CPUs and other 51refinements. 52Either chip can be used in either a 32-bit or 64-bit PCI 53slot. 54Communication with the chip is achieved via PCI shared memory 55and bus master DMA. 56The Tigon I and II support hardware multicast 57address filtering, VLAN tag extraction and insertion, and jumbo 58ethernet frames sizes up to 9000 bytes. 59Note that the Tigon I chipset 60is no longer in active production: all new adapters should come equipped 61with Tigon II chipsets. 62.Pp 63There are several PCI boards available from both Alteon and other 64vendors that use the Tigon chipset under OEM contract. 65The 66.Nm 67driver has been tested with the following Tigon-based adapters: 68.Bl -bullet -offset indent 69.It 70The Alteon AceNIC V gigabit ethernet adapter 71.It 72The 3Com 3c985-SX gigabit ethernet adapter 73.It 74The Netgear GA620 gigabit ethernet adapter 75.El 76.Pp 77The following should also be supported but have not yet been tested: 78.Bl -bullet -offset indent 79.It 80The Digital EtherWORKS 1000SX PCI Gigabit Adapter 81.It 82Silicon Graphics PCI gigabit ethernet adapter 83.El 84.Pp 85While the Tigon chipset supports 10, 100 and 1000Mbps speeds, support for 8610 and 100Mbps speeds is only available on boards with the proper 87transceivers. 88Most adapters are only designed to work at 1000Mbps, 89however the driver should support those NICs that work at lower speeds 90as well. 91.Pp 92Support for jumbo frames is provided via the interface MTU setting. 93Selecting an MTU larger than 1500 bytes with the 94.Xr ifconfig 8 95utility configures the adapter to receive and transmit jumbo frames. 96Using jumbo frames can greatly improve performance for certain tasks, 97such as file transfers and data streaming. 98.Pp 99Support for vlans is also available using the 100.Xr vlan 4 101mechanism. 102See the 103.Xr vlan 4 104man page for more details. 105.Pp 106The 107.Nm 108driver supports the following media types: 109.Pp 110.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 111.It autoselect 112Enable autoselection of the media type and options. 113The user can manually override 114the autoselected mode by adding media options to the 115.Pa /etc/rc.conf 116file. 117.It 10baseT/UTP 118Set 10Mbps operation. 119The 120.Ar mediaopt 121option can also be used to select either 122.Ar full-duplex 123or 124.Ar half-duplex modes. 125.It 100baseTX 126Set 100Mbps (fast ethernet) operation. 127The 128.Ar mediaopt 129option can also be used to select either 130.Ar full-duplex 131or 132.Ar half-duplex 133modes. 134.It 1000baseSX 135Set 1000Mbps (gigabit ethernet) operation. 136Only full 137.Ar full-duplex 138mode is supported at this speed. 139.El 140.Pp 141The 142.Nm 143driver supports the following media options: 144.Pp 145.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 146.It full-duplex 147Force full duplex operation 148.It half-duplex 149Force half duplex operation. 150.El 151.Pp 152For more information on configuring this device, see 153.Xr ifconfig 8 . 154.Sh DIAGNOSTICS 155.Bl -diag 156.It "ti%d: couldn't map memory" 157A fatal initialization error has occurred. 158.It "ti%d: couldn't map interrupt" 159A fatal initialization error has occurred. 160.It "ti%d: no memory for softc struct!" 161The driver failed to allocate memory for per-device instance information 162during initialization. 163.It "ti%d: failed to enable memory mapping!" 164The driver failed to initialize PCI shared memory mapping. 165This might 166happen if the card is not in a bus-master slot. 167.It "ti%d: no memory for jumbo buffers!" 168The driver failed to allocate memory for jumbo frames during 169initialization. 170.It "ti%d: bios thinks we're in a 64 bit slot, but we aren't" 171The BIOS has programmed the NIC as though it had been installed in 172a 64-bit PCI slot, but in fact the NIC is in a 32-bit slot. 173This happens 174as a result of a bug in some BIOSes. 175This can be worked around on the 176Tigon II, but on the Tigon I initialization will fail. 177.It "ti%d: board self-diagnostics failed!" 178The ROMFAIL bit in the CPU state register was set after system 179startup, indicating that the on-board NIC diagnostics failed. 180.It "ti%d: unknown hwrev" 181The driver detected a board with an unsupported hardware revision. 182The 183.Nm 184driver supports revision 4 (Tigon 1) and revision 6 (Tigon 2) chips 185and has firmware only for those devices. 186.It "ti%d: watchdog timeout" 187The device has stopped responding to the network, or there is a problem with 188the network connection (cable). 189.El 190.Sh SEE ALSO 191.Xr arp 4 , 192.Xr netintro 4 , 193.Xr vlan 4 , 194.Xr ifconfig 8 , 195.Xr ng_ether 8 196.Rs 197.%T Alteon Gigabit Ethernet/PCI NIC manuals
