This week I have add monitor mode on wtap(4) and add some fields in TX/RX
 radiotap header. Here is the patch: https://reviews.freebsd.org/D36469,
which contains the test plan.

I have also written test script in ath-sh(3), which can test all interface
modes created by wtap(4) (mesh, adhoc, sta, hostap, monitor), which locates
in src/tests/sys/net80211, means it can also test net80211 stack. Here is
the patch: https://reviews.freebsd.org/D36469.
