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 miibusdevice tx
Alternatively, to load the driver as a
module at boot time, place the following line in
loader.conf5:
if_tx_load="YES"
DESCRIPTION
The
driver provides support for the Ethernet adapters based on the
SMC 83c17x (EPIC) chips.
These are mostly SMC 9432 series cards.
The
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
driver supports the following media options:
full-duplex
Set full-duplex operation.
The
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
driver supports the VLAN operation (using
vlan(4)
interfaces) without decreasing the MTU on the
vlan(4)
interfaces.
