tcpdump would see packets before they are filtered. Of course the
driver and the net80211 stack might discard packets.

You can see more if you ask tcpdump to dump data link type IEEE802_11
and/or if you enable debug output. The stack is compiled with debugging
which can be enabled with sysctl:

net.link.ieee80211.debug: control debugging printfs
net.link.ieee80211.vap0.debug: control debugging printfs

The first it the default, the second is attached per access point
and controls the actual output.
