|
device driver supports Gigabit Ethernet interfaces based on the Intel
|
|
i8254x family of Gigabit Ethernet chips.
|
|

.Pp
|
|
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.
|
|
.Pp
|
|
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.
