svn commit: r256294 - head/sys/net80211

New Revision: 256294
URL: http://svnweb.freebsd.org/changeset/base/256294

Log:
  Fix the "am I a net80211 vap" check for bpf listeners.
  
  I changed it to use if_transmit a while ago but apparently with monitor
  mode the if_transmit method is overridden.
  
  This is (mostly) a workaround until a more permanent solution can be
  found.
