.Sh NAME
|
||||
.Nm txp
|
||||
.Nd 3Com 3XP Typhoon/Sidewinder (3CR990) Ethernet interface
|
||||
.Sh SYNOPSIS
|
||||
.Cd "txp* at pci? dev ? function ?"
|
||||
.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
|
||||
.It
|
||||
3Com 3CR990-TX-95
|
||||
.It
|
||||
3Com 3CR990-TX-97
|
||||
.It
|
||||
3Com 3CR990SVR95
|
||||
.It
|
||||
3Com 3CR990SVR97
|
||||
.El
|
||||
.Pp
|
||||
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
