|
|
.Nm txp
|
|
.Nd "3Com 3XP Typhoon/Sidewinder (3CR990) Ethernet interface"
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following line in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device txp"
|
|
.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_txp_load="YES"
|
|
.Ed
|
|
.Sh DEPRECATION NOTICE
|
|
The
|
|
.Nm
|
|
driver is not present in
|
|
.Fx 13.0
|
|
and later.
|
|
See https://github.com/freebsd/fcp/blob/master/fcp-0101.md for more
|
|
information.
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
interface provides access to the 10Mb/s and 100Mb/s Ethernet networks via the
|
|
.Tn 3Com
|
|
.Tn Typhoon/Sidewinder
|
|
chipset.
|
|
.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.
|
|
.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 indent
|
|
.It Cm media autoselect
|
|
Attempt to autoselect the media type (default)
|
|
.It Cm media 100baseTX mediaopt full-duplex
|
|
Use 100baseTX, full duplex
|
|
.It Cm media 100baseTX Op Cm mediaopt half-duplex
|
|
Use 100baseTX, half duplex
|
|
.It Cm media 10baseT mediaopt full-duplex
|
|
Use 10baseT, full duplex
|
|
.It Cm media 10baseT Op Cm mediaopt half-duplex
|
|
Use 10baseT, half duplex
