We've discovered a number of bugs in the 6LoWPAN dissector, and have fixed them
in the following patch. The fixed bugs include:
  - Incorrect UDP Checksum calculation.
  - Incorrect link-local prefix when decompressing IPHC headers.
  - Incorrect parsing of the UDP port numbers when not 8-byte aligned.
  - Overflow of the datagram offset field when reassembling fragmented packets.
