Ethernet Types
The 13th and 14th octets of an Ethernet or IEEE802.3 packet (after the preamble)
consist of the "Ethernet Type" or "IEEE802.3 Length" field.
The "Ethernet Type" values are managed by XEROX. Some assignments are
public, others private.
@ Packets below 0600h are assumed to be 802.3, packets greater than 0600h to be
Ethernet.
+ These protocols are mentioned by Xerox. Only vendors are listed, not what protocols.
* These protocols use Ethernet broadcast, where multicast would be preferable.
% Possible Private Protocols, i.e. not registered
