# =head1 REFERENCE
# 
# RFC2460
# 
# 4.7 No Next Header
# 
#    The value 59 in the Next Header field of an IPv6 header or any
#    extension header indicates that there is nothing following that
#    header.  If the Payload Length field of the IPv6 header indicates the
#    presence of octets past the end of a header whose Next Header field
#    contains 59, those octets must be ignored, and passed on unchanged if
#    the packet is forwarded.
