    sys/netinet6         udp6_usrreq.c 
  Log:
  Attempt to improve feature parity between UDPv4 and UDPv6 by merging
  UDPv4 features to UDPv6:
  
  - Add MAC checks on delivery and MAC labeling on transmit.
  - Check for (and reject) datagrams with destination port 0.
  - For multicast delivery, check the source port only if the socket being
    considered as a destination has been connected.
  - Implement UDP blackholing based on net.inet.udp.blackhole.
  - Add a new ICMPv6 unreachable reply rate limiting category for failed
    delivery attempts and implement rate limiting for UDPv6 (submitted by
    bz).
