Directed IPX Packet
A valid directed IPX packet contains:
• The station's MAC address.
• A protocol type of 0x8137.
• an IPX node address that equals the station's MAC address.
It might 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.
