NAME
wm
- Intel i8254x Gigabit Ethernet driver
SYNOPSIS
wm* at pci? dev ? function ?
Configuration of PHYs may also be necessary. See
mii(4).

In addition to Intel's own
``PRO/1000''
line of Gigabit Ethernet interfaces, these chips also appear on
some server systems, processor evaluation boards, and in embedded
systems.
The i8254x supports IPv4/TCP/UDP checksumming and TCP segmentation
in hardware.
The
wm
driver supports these features of the chip.
See
ifconfig(8)
for information on how to enable this feature.
