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