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

NAME
     tx	-- SMC 83c17x Fast Ethernet device driver

SYNOPSIS
     To	compile	this driver into the kernel, place the following lines in your
     kernel configuration file:

	   device miibus
	   device tx

     Alternatively, to load the	driver as a module at boot time, place the
     following line in loader.conf(5):

	   if_tx_load="YES"

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.
