New Revision: 213621
URL: http://svn.freebsd.org/changeset/base/213621

Log:
  MFC r212117,212119:
  rr212117:
    Report result of link state change to caller. Previously it always
    returned success.
  
  r212119:
    Do not reinitialize controller whenever promiscuous mode or
    allmulti is toggled. Controller does not require reinitialization.
    This removes unnecessary controller reinitialization whenever
    tcpdump is used.
    While I'm here remove unnecessary variable reinitialization.
