Author: adrian Date: Thu Oct 10 19:56:31 2013 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.
