The Gigabit Ethernet function is compliant to IEEE802.3 Media Access Controller, and IEEE 802.3u 1000BASE-T/100BASE-TX/10BASE-T. The MAC supports IP
V4, IPV6, TCP, UDP checksum, segmentation task-offload, priority encoding and IE
EE802.1Q VLAN features. It also supports Receive Side Scaling (RSS) to balance the loading for received data processing across multiple CPUs. The Ethernet
function supports remote wakeup (including AMD Magic Packet™ and Microsoft
