  UDPTERM SMF records do not contain the correct remote IP address
  and PORT for IPv6 sockets.
  
  The SMFCONFIG TYPE119 UDPTERM profile setting creates an SMF
  type 119 subtype 10 record to be written when a UDP socket is
  closed.  The SMF119UD_UCRIP field is supposed to contain the
  remote IP address of the last datagram received.  The
  SMF119UD_UCRPORT field is supposed to contain the remote port
  of the last datagram received.  These values are not being
  set correctly for IPv6 UDP sockets.

Problem conclusion

• EZBUDSMF has been amended to set SMF119UD_UCRIP with the remote
  IP address of the last datagram received on an IPv6 socket, and
  SMF119UD_UCRPORT with the remote port of the last datagram
  received.
