3.3.2.3.2.2 Directed IPX Packet
A valid Directed IPX packet contains the station's MAC address, a Protocol Type of 0x8137, and an IPX
Node Address that equals to the station's MAC address. It can also include LLC/SNAP Headers and VLAN
Tags. Since filtering this packet relies on the flexible filters, which use offsets specified by the operating
system directly, the operating system must account for the extra offset LLC/SNAP Headers and VLAN
tags.

3.3.2.3.2.3 IPv6 Neighbor Discovery Filter
In IPv6, a neighbor discovery packet is used for address resolution. A flexible filter can be used to check
for a neighbor discovery packet.
3.3.2.3.3 Wake-Up Packet Storage
The 82598 saves the first 128-byte of the wake-up packet in its internal buffer, which can be read
through the WUPM register after the system wakes up.
