NAME
tx —
SMC 83c17x Fast Ethernet device
driver
SYNOPSIS
device miibus
device tx
DESCRIPTION
Thetx 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.
