37.5.10.3.6 Directed IPv4 Packet
The LAN controller will support reception of Directed IPv4 packets for wake up if the
IPV4 bit is set in the Wake Up Filter Control Register (WUFC). Four IPv4 addresses are
supported which are programmed in the IPv4 Address Table (IP4AT). A successfully
matched packet must contain the station's MAC address, a Type of 0x0800, and one of
the four programmed IPv4 addresses. The GbE controller also handles Directed IPv4
packets that have VLAN tagging on both Ethernet II and Ethernet SNAP types.
