     tx -- SMC 83c17x Fast Ethernet device driver

SYNOPSIS    [Toc]    [Back]

     device miibus
     device tx

DESCRIPTION    [Toc]    [Back]

     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    [Toc]    [Back]
     The tx driver supports the VLAN operation (using vlan(4) interface) without
 decreasing the MTU on the vlan(4) interfaces.

DIAGNOSTICS    [Toc]    [Back]

     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 reseting, driver failed to stop device
     correctly.

BUGS    [Toc]    [Back]

     The auto-negotiation does not work very well.
