.Sh SYNOPSIS
|
||
|
|
.Cd "device txp"
|
||
|
|
.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
interface provides access to the 10Mb/s and 100Mb/s Ethernet networks via the
|
||
|
|
.Tn 3Com
|
||
|
|
.Tn Typhoon/Sidewinder
|
||
|
|
chipset.
|
||
|
|
This driver supports the following cards:
|
||
|
|
.Pp
|
||
|
|
.Bl -bullet -offset indent -compact
|

|
|
Basic Ethernet functions are provided as well as support for
|
||
|
|
.Xr vlan 4
|
||
|
|
tag removal and insertion assistance, receive
|
||
|
|
.Xr ip 4 ,
|
||
|
|
.Xr tcp 4 ,
|
||
|
|
and
|
||
|
|
.Xr udp 4
|
||
|
|
checksum offloading,
|
||
|
|
and
|
||
|
|
transmit
|
||
|
|
.Xr ip 4
|
||
|
|
checksum offloading.
|
||
|
|
There is currently no support for
|
||
|
|
transmit
|
||
|
|
.Xr tcp 4
|
||
|
|
or
|
||
|
|
.Xr udp 4
|
||
|
|
checksum offloading,
|
||
|
|
.Xr tcp 4
|
||
|
|
segmentation, nor
|
||
|
|
.Xr ipsec 4
|
||
|
|
acceleration.
|
||
|
|
Note that hardware checksumming is only used when the interface is not
|
||
|
|
in
|
||
|
|
.Xr bridge 4
|
||
|
|
mode.
|
||
|
|
.Pp
|
||
|
|
Each of the host's network addresses
|
||
|
|
is specified at boot time with an
|
||
|
|
.Dv SIOCSIFADDR
|
||
|
|
.Xr ioctl 2 .
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
interface employs the address resolution protocol described in
|
||
|
|
.Xr arp 4
|
||
|
|
to dynamically map between Internet and Ethernet addresses on the local
|
||
|
|
network.
|
||
|
|
.Pp
|
||
|
|
When a
|
||
|
|
.Nm
|
||
|
|
interface is brought up, by default, it will attempt to auto-negotiate the
|
||
|
|
link speed and duplex mode. The speeds, in order of attempt, are:
|
||
|
|
100Mb/s Full Duplex, 100Mb/s Half Duplex, 10 Mb/s Full Duplex, and
|
||
|
|
10 Mb/s Half Duplex.
|
||
|
|
.Pp
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
supports several media types, which are selected via the
|
||
|
|
.Xr ifconfig 8
|
||
|
|
command.
|
||
|
|
The supported media types are:
|
||
|
|
.Bl -tag -width xxxxxxxxxxxxxx -offset indent
|
||
|
|
.It media autoselect
|
||
|
|
Attempt to autoselect the media type (default)
|
||
|
|
.It media 100baseTX mediaopt full-duplex
|
||
|
|
Use 100baseTX, full duplex
|
||
|
|
.It media 100baseTX Op mediaopt half-duplex
|
||
|
|
Use 100baseTX, half duplex
|
||
|
|
.It media 10baseT mediaopt full-duplex
|
||
|
|
Use 10baseT, full duplex
|
||
|
|
.It media 10baseT Op mediaopt half-duplex
|
||
|
|
Use 10baseT, half duplex
