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 txAlternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
if_tx_load="YES"
DEPRECATION NOTICE
Thetx driver is not present in FreeBSD
13.0 and later. See
https://github.com/freebsd/fcp/blob/master/fcp-0101.md for more information.
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.
