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.
