Directed IPv4 Packet
The 82577 supports receiving Directed IPv4 packets for wake up if the IPV4 bit (bit 6)
is set in the WUFC register. Three 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 Protocol Type of 0x0800, and one of the four
programmed Ipv4 addresses. The 82577 also handles Directed IPv4 packets that have
VLAN tagging on both Ethernet II and Ethernet SNAP types.
Directed IPv6 Packet
The 82577 supports receiving Directed IPv6 packets for wake up if the IPV6 bit (bit 7)
is set in the WUFC register. One IPv6 address is supported, which 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
82577 also handles Directed IPv6 packets that have VLAN tagging on both Ethernet II
and Ethernet SNAP types.
