NAME



txp

 - 3Com 3XP Typhoon/Sidewinder (3CR990) Ethernet interface

SYNOPSIS

To compile this driver into the kernel, place the following line in your kernel configuration file:

device txp

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:

if_txp_load="YES"

DESCRIPTION

The interface provides access to the 10Mb/s and 100Mb/s Ethernet networks via the 3Com Typhoon/Sidewinder chipset.

Basic Ethernet functions are provided as well as support for vlan(4) tag removal and insertion assistance, receive ip(4), tcp(4), and udp(4) checksum offloading, and transmit ip(4) checksum offloading. There is currently no support for transmit tcp(4) or udp(4) checksum offloading, tcp(4) segmentation, nor ipsec(4) acceleration.

Each of the host's network addresses is specified at boot time with an SIOCSIFADDR ioctl(2). The interface employs the address resolution protocol described in arp(4) to dynamically map between Internet and Ethernet addresses on the local network.

When a 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.

The supports several media types, which are selected via the ifconfig(8) command. The supported media types are:
