TX(4) BSD/i386 Kernel Interfaces Manual TX(4)NAMEtx — SMC 83c17x Fast Ethernet device driver
SYNOPSIS
device miibus
device txDESCRIPTION
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.
