TX(4) BSD Programmer's Manual TX(4)NAMEtx - SMC 9432 10/100 Mbps Ethernet driver
SYNOPSIS
tx* at pci? dev ? function ?
DESCRIPTION
The tx interface provides access to the 10Mb/s and 100Mb/s Ethernet net-
works via the SMC EPIC chipset. This driver provides support for the SMC
EtherPower II 10/100 Ethernet cards.
Each of the host's network addresses is specified at boot time with an
SIOCSIFADDR ioctl(2). The tx interface employs the address resolution
protocol described in arp(4) to dynamically map between Internet and Eth-
ernet addresses on the local network.
When a tx interface is brought up, by default, it will attempt to auto-
negotiate the link speed and duplex. 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 tx 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 100baseFX mediaopt full-duplex
Use 100baseFX (fiber), full duplex
media 100baseFX [mediaopt half-duplex]
Use 100baseFX (fiber), half duplex
media 100baseTX mediaopt full-duplex
Use 100baseTX, full duplex
media 100baseTX [mediaopt half-duplex]
Use 100baseTX, half duplex
media 100baseTX mediaopt loopback
Put the interface into loopback mode
media 10baseT mediaopt full-duplex
Use 10baseT, full duplex
media 10baseT [mediaopt half-duplex]
Use 10baseT, half duplex
media 10baseT mediaopt loopback
Put the interface into loopback mode
DIAGNOSTICS
tx%d: device timeout %d packets The device stopped responding. Device
and driver reset follows this error.
tx%d: PCI fatal error occurred (%s) One of following errors occurred:
PCI Target Abort, PCI Master Abort, Data Parity Error or Address Parity
Error. Device and driver reset follows this error.
tx%d: WARNING! no link established No media connected. Displayed at
startup only.
tx%d: cannot allocate mbuf header/cluster Failed to allocate memory for
a received packet. Packet was dropped.
tx%d: can't stop %s DMA While resetting, the driver failed to stop the
device correctly.

OpenBSD support for the tx first appeared in OpenBSD 2.4.
BUGS
Multicast packet filtering is not supported.
