  3. If NS received then send NA, and wait Echo Reply again
  4. Receive Echo Reply

# 3.  IPv6 Header Format
# 
#    Payload Length       16-bit unsigned integer.  Length of the IPv6
#                         payload, i.e., the rest of the packet following
#                         this IPv6 header, in octets.  (Note that any

#                         considered part of the payload, i.e., included
#                         in the length count.)
