45 * Following the 2byte BRCM ether_type is a 16bit BRCM subtype field
46 * in one of two formats: (only subtypes 32768-65535 are in use now)
49 * 8 bit subtype (0-127)
50 * 8 bit length in bytes (0-255)
52 * subtypes 32768-65535:
53 * 16 bit big-endian subtype
54 * 16 bit big-endian length in bytes (0-65535)
56 * length is the number of additional bytes beyond the 4 or 6 byte header
60 * 5-15 reserved for iLine protocol assignments
61 * 17-126 reserved, assignable
64 * 32769-65534 reserved, assignable
69 * While adding the subtypes and their specific processing code make sure
70 * bcmeth_bcm_hdr_t is the first data structure in the user specific data structure definition
