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.
