|
|
.Nd Sundance/Tamarack TC9021 Gigabit Ethernet adapter driver
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device miibus"
|
|
.Cd "device stge"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
if_stge_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
device driver provides support for various NICs based on the
|
|
Sundance/Tamarack TC9021 Gigabit Ethernet controller chip.
|
|
.Pp
|
|
The Sundance/Tamarack TC9021 is found on the D-Link DGE-550T
|
|
and the Antares Microsystems Gigabit Ethernet board.
|
|
It uses an external PHY or an external 10-bit interface.
|
|
.Pp
|
|
All NICs supported by the
|
|
.Nm
|
|
driver have TCP/UDP/IP checksum offload for both receive and
|
|
transmit, hardware VLAN tag stripping/insertion features, and
|
|
receive interrupt moderation mechanism as well as a 64-bit
|
|
multicast hash filter.
|
|
The Sundance/Tamarack TC9021 supports TBI (ten bit interface)
|
|
and GMII transceivers, which means it can be used with either
|
|
copper or 1000baseX fiber applications.
|
|
.Pp
|
|
The Sundance/Tamarack TC9021 also supports jumbo frames, which can be
|
|
configured 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.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media types:
|
|
.Bl -tag -width ".Cm 10baseT/UTP"
|
|
.It Cm autoselect
|
|
Enable autoselection of the media type and options.
|
|
The user can manually override
|
|
the autoselected mode by adding media options to
|
|
.Xr rc.conf 5 .
|
|
.It Cm 10baseT/UTP
|
|
Set 10Mbps operation.
|
|
The
|
|
.Xr ifconfig 8
|
|
.Cm mediaopt
|
|
option can also be used to select either
|
|
.Cm full-duplex
|
|
or
|
|
.Cm half-duplex
|
|
modes.
|
|
.It Cm 100baseTX
|
|
Set 100Mbps (Fast Ethernet) operation.
|
|
The
|
|
.Xr ifconfig 8
|
|
.Cm mediaopt
|
|
option can also be used to select either
|
|
.Cm full-duplex
|
|
or
|
|
.Cm half-duplex
|
|
modes.
|
|
.It Cm 1000baseTX
|
|
Set 1000baseTX operation over twisted pair.
|
|
The Sundance/Tamarack supports 1000Mbps in
|
|
.Cm autoselect
|
|
mode only.
|
|
.\" .It Cm 1000baseSX
|
|
.\" Set 1000Mbps (Gigabit Ethernet) operation.
|
|
.\" Both
|
|
.\" .Cm full-duplex
|
|
.\" and
|
|
.\" .Cm half-duplex
|
|
.\" modes are supported.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media options:
|
|
.Bl -tag -width ".Cm full-duplex"
|
|
.It Cm full-duplex
|
|
Force full duplex operation.
|
|
.It Cm half-duplex
|
|
Force half duplex operation.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver also supports one special link option for 1000baseTX cards:
|
|
.Bl -tag -width ".Cm link0"
|
|
.It Cm link0
|
|
With 1000baseTX cards, establishing a link between two ports requires
|
|
that one port is configured as master and the other one as slave.
|
|
With autonegotiation,
|
|
the master/slave settings will be chosen automatically.
|
|
However when manually selecting the link state, it is necessary to
|
|
force one side of the link to be a master and the other a slave.
|
|
The
|
|
.Nm
|
|
driver configures the ports as slaves by default.
|
|
Setting the
|
|
.Cm link0
|
|
flag with
|
|
.Xr ifconfig 8
|
|
will set a port as a master instead.
|
|
.El
|
|

|

|
|
.Xr ifconfig 8 .
