BE(4)							   BSD Kernel Interfaces Manual 						     BE(4)

be -- SPARC Fast Ethernet interface SYNOPSIS
qec* at sbus? slot ? offset ? be* at qec? DESCRIPTION
The be interface provides access to the 10Mb/s and 100Mb/s (half duplex only) Ethernet networks. The be is found on the Sun 10/100 Mbit Eth- ernet boards (Sun part number SUNW,501-2450). Each of the host's network addresses is specified at boot time with an SIOCSIFADDR ioctl(2). The be interface employs the address resolution protocol described in arp(4) to dynamically map between Internet and Ethernet addresses on the local network. The be is not capable of link autonegotiation, so a media type must be specified with ifconfig(8). The supported media types are: media 100baseTX Use 100Mbps, half duplex media 10baseT Use 10Mbps, half duplex SEE ALSO
arp(4), ifmedia(4), inet(4), intro(4), netintro(4), sbus(4), ifconfig(8) HISTORY
Support for the be first appeared in NetBSD 1.4. BSD
March 31, 2004 BSD

TXP(4)							   BSD Kernel Interfaces Manual 						    TXP(4)

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.conf(5): if_txp_load="YES" DESCRIPTION
The txp 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 offload- ing, 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 txp interface employs the address resolu- tion protocol described in arp(4) to dynamically map between Internet and Ethernet addresses on the local network. When a txp 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 txp supports several media types, which are selected via the ifconfig(8) command. The supported media types are: media autoselect Attempt to autoselect the media type (default) media 100baseTX mediaopt full-duplex Use 100baseTX, full duplex media 100baseTX [mediaopt half-duplex] Use 100baseTX, half duplex media 10baseT mediaopt full-duplex Use 10baseT, full duplex media 10baseT [mediaopt half-duplex] Use 10baseT, half duplex HARDWARE
The txp driver supports the following cards: o 3Com 3CR990-TX-95 o 3Com 3CR990-TX-97 o 3Com 3cR990B-TXM o 3Com 3CR990SVR95 o 3Com 3CR990SVR97 o 3Com 3cR990B-SRV SEE ALSO
altq(4), arp(4), inet(4), intro(4), ip(4), miibus(4), tcp(4), udp(4), vlan(4), ifconfig(8) HISTORY
The txp driver first appeared in OpenBSD 2.9. BSD
