media option generally should be used instead. Actually I think the lists of media types should be removed from the manual pages of MAC drivers altogether and users just pointed to the output of `ifconfig -m` instead; even before r215297 there were several outdated descriptions, technically it's wrong most of the time as not the MAC drivers support these media types but actually the PHY drivers do and it generally doesn't make sense to maintain these lists in every manual page of a driver as the media is auto-detected.

.Nm stge
|
|
.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.
|
|
