wmIntel i8254x Gigabit Ethernet driver

SYNOPSIS

wm* at pci? dev ? function ?

Configuration of PHYs may also be necessary. See mii(4).

DESCRIPTION

The wm device driver supports Gigabit Ethernet interfaces based on the Intel i8254x family of Gigabit Ethernet chips. The interfaces supported by the wm driver include:

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 i825[478]x 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.
