New Revision: 315611
URL: https://svnweb.freebsd.org/changeset/base/315611

Log:
  MFC r315206:
  
  bsnmpd: fix segfault when trans_insert_port(..) is called with multiple
  out of order addresses
  
  Move `port->transport` initialization before the TAILQ_FOREACH(..) loop
  to ensure that the value is properly initialized before it's inserted
  into the TAILQ.
