Cisco CDP packets appears to be sent as LLC packets with an OUI of
0x00000c and a protocol ID of 0x2000 - we used to recognize those as CDP
because we ignored the OUI and treated all LLC packets as
SNAP-encapsulated packets, and treated 0x2000 as an Ethertype, but we
now treat only encapsulated-Ethernet and Apple packets as
SNAP-encapsulated (and arguably we should handle Apple separately).
