|
|
Alteon Networks Tigon I and Tigon II gigabit ethernet driver
|
|
.Sh SYNOPSIS
|
|
.Cd "device ti"
|
|
.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).
