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 the vlan(4) interface) 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 reseting, driver failed to stop device correctly.
