the Wakeup Filter Control Register (WUFC). One IPv6 address is supported and it is programmed
in the IPv6 Address Table (IPv6AT). A successfully matched packet must contain the station’s
in the IPv6 Address Table (IPv6AT). A successfully matched packet must contain the station’s
MAC address, a Protocol Type of 0800h, and the programmed IPv6 address. The Ethernet
controller also handles Directed IPv6 packets that have VLAN tagging on both Ethernet II and
Ethernet SNAP types.
