New Revision: 349429
URL: https://svnweb.freebsd.org/changeset/base/349429

Log:
  Merge from stable/11:
    Fix the uninitialized use of source IPv6 address in NAT64LSN.
  
    This code is already refactored in head/, but due to the missing
    epoch(9) support it is impossible to merge. So, it is direct commit to
    stable/11.
