SYNOPSIS 40.Cd "device ti" 41.Sh DESCRIPTION 42The 43.Nm 44driver provides support for PCI gigabit ethernet adapters based on 45the Alteon Networks Tigon gigabit ethernet controller chip. 46The Tigon 47contains an embedded R4000 CPU, gigabit MAC, dual DMA channels and 48a PCI interface unit. 49The Tigon II contains two R4000 CPUs and other 50refinements. 51Either chip can be used in either a 32-bit or 64-bit PCI 52slot. 53Communication with the chip is achieved via PCI shared memory 54and bus master DMA. 55The Tigon I and II support hardware multicast 56address filtering, VLAN tag extraction and insertion, and jumbo 57ethernet frames sizes up to 9000 bytes. 58Note that the Tigon I chipset 59is no longer in active production: all new adapters should come equipped 60with Tigon II chipsets. 61.Pp 62There are several PCI boards available from both Alteon and other 63vendors that use the Tigon chipset under OEM contract. 64The 65.Nm 66driver has been tested with the following Tigon-based adapters: 67.Pp 68.Bl -bullet -compact -offset indent 69.It 70The Alteon AceNIC V gigabit ethernet adapter (1000baseSX) 71.It 72The Alteon AceNIC V gigabit ethernet adapter (1000baseT) 73.It 74The 3Com 3c985-SX gigabit ethernet adapter (Tigon 1) 75.It 76The 3Com 3c985B-SX gigabit ethernet adapter (Tigon 2) 77.It 78The Netgear GA620 gigabit ethernet adapter (1000baseSX) 79.It 80The Netgear GA620T gigabit ethernet adapter (1000baseT) 81.El 82.Pp 83The following should also be supported but have not yet been tested: 84.Pp 85.Bl -bullet -compact -offset indent 86.It 87The Digital EtherWORKS 1000SX PCI Gigabit Adapter 88.It 89Silicon Graphics PCI gigabit ethernet adapter 90.It 91Farallon PN9000SX Gigabit Ethernet adapter 92.El 93.Pp 94While the Tigon chipset supports 10, 100 and 1000Mbps speeds, support for 9510 and 100Mbps speeds is only available on boards with the proper 96transceivers. 97Most adapters are only designed to work at 1000Mbps, 98however the driver should support those NICs that work at lower speeds 99as well. 100.Pp 101Support for jumbo frames is provided via the interface MTU setting. 102Selecting an MTU larger than 1500 bytes with the 103.Xr ifconfig 8 104utility configures the adapter to receive and transmit jumbo frames. 105Using jumbo frames can greatly improve performance for certain tasks, 106such as file transfers and data streaming. 107.Pp 108Support for vlans is also available using the 109.Xr vlan 4 110mechanism. 111See the 112.Xr vlan 4 113man page for more details. 114.Pp 115The 116.Nm 117driver supports the following media types: 118.Pp 119.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 120.It autoselect 121Enable autoselection of the media type and options. 122The user can manually override 123the autoselected mode by adding media options to the 124.Pa /etc/rc.conf 125file. 126.It 10baseT/UTP 127Set 10Mbps operation. 128The 129.Ar mediaopt 130option can also be used to select either 131.Ar full-duplex 132or 133.Ar half-duplex 134modes. 135.It 100baseTX 136Set 100Mbps (fast ethernet) operation. 137The 138.Ar mediaopt 139option can also be used to select either 140.Ar full-duplex 141or 142.Ar half-duplex 143modes. 144.It 1000baseSX 145Set 1000Mbps (gigabit ethernet) operation. 146Only full 147.Ar full-duplex 148mode is supported at this speed. 149.El 150.Pp 151The 152.Nm 153driver supports the following media options: 154.Pp 155.Bl -tag -width xxxxxxxxxxxxxxxxxxxx 156.It full-duplex 157Force full duplex operation 158.It half-duplex 159Force half duplex operation. 160.El 161.Pp 162For more information on configuring this device, see 163.Xr ifconfig 8 . 164.Sh DIAGNOSTICS 165.Bl -diag 166.It "ti%d: couldn't map memory" 167A fatal initialization error has occurred. 168.It "ti%d: couldn't map interrupt" 169A fatal initialization error has occurred. 170.It "ti%d: no memory for softc struct!" 171The driver failed to allocate memory for per-device instance information 172during initialization. 173.It "ti%d: failed to enable memory mapping!" 174The driver failed to initialize PCI shared memory mapping. 175This might 176happen if the card is not in a bus-master slot. 177.It "ti%d: no memory for jumbo buffers!" 178The driver failed to allocate memory for jumbo frames during 179initialization. 180.It "ti%d: bios thinks we're in a 64 bit slot, but we aren't" 181The BIOS has programmed the NIC as though it had been installed in 182a 64-bit PCI slot, but in fact the NIC is in a 32-bit slot. 183This happens 184as a result of a bug in some BIOSes. 185This can be worked around on the 186Tigon II, but on the Tigon I initialization will fail. 187.It "ti%d: board self-diagnostics failed!" 188The ROMFAIL bit in the CPU state register was set after system 189startup, indicating that the on-board NIC diagnostics failed. 190.It "ti%d: unknown hwrev" 191The driver detected a board with an unsupported hardware revision. 192The 193.Nm 194driver supports revision 4 (Tigon 1) and revision 6 (Tigon 2) chips 195and has firmware only for those devices. 196.It "ti%d: watchdog timeout" 197The device has stopped responding to the network, or there is a problem with 198the network connection (cable). 199.El 200.Sh SEE ALSO 201.Xr arp 4 , 202.Xr netintro 4 , 203.Xr ng_ether 4 , 204.Xr vlan 4 , 205.Xr ifconfig 8 206.Rs 207.%T Alteon Gigabit Ethernet/PCI NIC manuals
