brooks d4f6b392d7 Deprecate a number of less used 10 and 10/100 Ethernet devices.
The current deprecated list is: ae, bm, cs, de, dme, ed, ep, ex, fe,
pcn, sf, sn, tl, tx, txp, vx, wb, xe

The list as refined as part of FCP-0101. Per the FCP, devices may be
removed from the deprecation list if enough users are found or they are
converted to iflib.

.Sh NAME
.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

.Nm
driver supports the following cards:
