Values for IPX packet type:
 00h	unknown packet type
 01h	routing information packet
 02h	echo packet
 03h	error packet
 04h	packet exchange packet (always use this one for data)
 05h	SPX packet (see #03826)
 11h	NetWare Core Protocol (also used by Service Advertising Protocol)
 14h	Propagated Packet (for NetWare), NetBIOS name packet
 15h-1Eh experimental protocols
Note:	undocumented packet type 14h will cross up to 16 networks deep in
	  all directions; as Aaron Martin of Origin Systems discovered, the
	  first 64 bytes of the IPX data in such packets should be considered
	  reserved, as IPX places the traversed server nodes there.
