     tx - SMC 9432 10/100 Mbps Ethernet driver

SYNOPSIS    [Toc]    [Back]

     tx* at pci? dev ? function ?

DESCRIPTION    [Toc]    [Back]

     The tx interface provides access to the 10Mb/s  and  100Mb/s
Ethernet networks
  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 Ethernet
 addresses on the local network.

     When  a  tx interface is brought up, by default, it will attempt to autonegotiate
 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    [Toc]    [Back]

     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.
