TX(4)                      BSD Programmer's Manual                       TX(4)

NAME

     tx - 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.

HISTORY

     OpenBSD support for the tx first appeared in OpenBSD 2.4.

BUGS

     Multicast packet filtering is not supported.
