TX(4)               FreeBSD Kernel Interfaces Manual (i386)              TX(4)

NAME
     tx - SMC 83c17x Fast Ethernet device driver

SYNOPSIS
     device miibus
     device tx

DESCRIPTION
     The tx driver provides support for the Ethernet adapters based on the SMC
     83c17x (EPIC) chips.  These are mostly SMC 9432 series cards.

     The tx driver supports the following media types (depending on card's
     capabilities):

     autoselect       Enable autonegotiation (default)

     100baseFX        Set 100Mbps (fast ethernet) fiber optic operation

     100baseTX        Set 100Mbps (fast ethernet) twisted pair operation

     10baseT/UTP      Set 10Mbps on 10baseT port

     10base2/BNC      Set 10Mbps on 10base2 port

     The tx driver supports the following media options:

     full-duplex      Set full-duplex operation

     Driver supports oversized ethernet packets (up to 1600 bytes).  Refer to
     the ifconfig(8) man page on setting the interface's MTU.

     The old ``ifconfig tx0 linkN'' method of configuration is not supported.

   VLAN (IEEE 802.1Q) support
     The tx driver supports the VLAN operation (using vlan(4) inteface)
     without decreasing the MTU on the vlan(4) interfaces.

DIAGNOSTICS
     tx%d: device timeout %d packets  The device stops responding.  Device and
     driver reset follows this error.

     tx%d: PCI fatal error occured (%s)  One of following errors occured: PCI
     Target Abort, PCI Master Abort, Data Parity Error or Address Parity
     Error.  Device and driver reset follows this error.

     tx%d: cannot allocate mbuf header/cluster  Cannot allocate memory for
     received packet.  Packet thrown away.

     tx%d: can't stop %s DMA  While reseting, driver failed to stop device
     correctly.

BUGS
     The multicast packets filtering is not supported.
