/SPEED=value
Sets the speed of the LAN.
Valid values are 10, 100, 1000, 10000, or autonegotiate; the last
choice, autonegotiate, selects the 10 Mb/s for Ethernet, 100 Mb/s
for Fast Ethernet, 1000 Mb/s for Gigabit Ethernet, and 10000 Mb/s
for 10-Gigabit Ethernet. If you select autonegotiate, the LAN
driver repeats autonegotiation.
