  Modified files:
    sys/netinet          udp_usrreq.c 
  Log:
  When verifying the IPv4 UDP checksum, don't overwrite the checksum
  value in the mbuf with the result of the calculation. Previously,
  if we chose to return an ICMP message, the quoted UDP checksum bytes
  would be different to what was sent.
