Directed IPv6 Packet
The 82574L supports receiving directed IPv6 packets for wake up if the IPV6 bit is set
in the WUFC. One IPv6 address is supported and is programmed in the IPv6 Address
Table (IP6AT). A successfully matched packet must contain the station's MAC address,
a protocol type of 0x0800, and the programmed IPv6 address. The 82574L also
handles directed IPv6 packets that have VLAN tagging on both Ethernet II and Ethernet
SNAP types.
