Networks Tigon 1 and Tigon 2 chipsets. There are a _lot_ of OEM'ed gigabit ethernet adapters out there which use the Alteon chipset so this driver covers a fair amount of hardware. I know that it works with the Alteon AceNIC, 3Com 3c985 and Netgear GA620, however it should also work with the DEC/Compaq EtherWORKS 1000, Silicon Graphics Gigabit ethernet board, NEC Gigabit Ethernet board and maybe even the IBM and and Sun boards. The Netgear board is the cheapest (~$350US) but still yields fairly good performance. Support is provided for jumbo frames with all adapters (just set the MTU to something larger than 1500 bytes), as well as hardware multicast filtering and vlan tagging (in conjunction with the vlan support in -current, which I should merge into -stable soon). There are some hooks for checksum offload support, but they're turned off for now since FreeBSD doesn't have an officially sanctioned way to support checksum offloading (yet). I have not added the 'device ti0' entry to GENERIC since the driver with all the firmware compiled in is quite large, and it doesn't really fit into the category of generic hardware.

Alteon Networks Tigon I and Tigon II gigabit ethernet driver
|
|
.Sh SYNOPSIS
|
|
.Cd "device ti0"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for PCI gigabit ethernet adapters based on
|
|
the Alteon Networks Tigon gigabit ethernet controller chip. 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
|
|
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 ethernet adapter
|
|
.It
|
|
The 3Com 3c985-SX gigabit ethernet adapter
|
|
.It
|
|
The Netgear GA620 gigabit ethernet adapter
|
|
.El
|
|
.Pp
|
|
The following should also be supported but have not yet been tested:
|
|
.Bl -bullet -offset indent
|
|
.It
|
|
The Digital EtherWORKS 1000SX PCI Gigabit Adapter
|
|
.It
|
|
Silicon Graphics PCI gigabit 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
|
|
Support for vlans is also available using the
|
|
.Xr vlan 4
|
|
mechanism. See the
|
|
.Xr vlan 4
|
|
man page for more details.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media types:
|
|
.Pp
|
|
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
|
|
.It autoselect
|
|
Enable autoselection of the media type and options.
|
|
The user can manually override
|
|
the autoselected mode by adding media options to the
|
|
.Pa /etc/rc.conf
|
|
file.
|
|
.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 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) 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.

.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).
