TX(4)                  FreeBSD Kernel Interfaces Manual                  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.

     The tx 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) interfaces)
     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 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: cannot allocate mbuf header/cluster  Cannot allocate memory for
     received packet.  Packet thrown away.

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

BUGS
     The auto-negotiation does not work very well.
