  The address TLV looks as follows:

          +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
          |                    Number of addresses                        |
          +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
          |                   IDRP encoded address                        |
          +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

	  An address is encoded in IDRP format:

	   0                   1                   2                   3
           0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
          +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
          |       PT      |    PT Length  |    Protocol (variable) ...
          +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
          |        Address length         |    Address (variable) ...
          +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

	  PT: Protocol type
	      1 = NLPID format
              2 = 802.2 format

	  PT Length:
	      Length of protocol field, 1 for PT = 1, and either 3 or 8 for
	      802.2 format depending if SNAP is used for PT = 2.

	      The encodings for the other protocols have the following format:

          field:    <SSAP><DSAP><CTRL><-------OUI------><protocl_TYPE>
                    |     |     |     |     |     |     |     |      |
          bytes:    0     1     2     3     4     5     6     7      8

          where the first 3 bytes are 0xAAAA03 for SNAP encoded addresses.
          The OUI is 000000 for ethernet and <protocl_TYPE>
          is the assigned Ethernet type code for the particular protocol.
          e.g. for DECnet the encoding is AAAA03 000000 6003.
               for IPv6   the encoding is AAAA03 000000 86DD
