--- Comment #4 from Bjoern A. Zeeb <bz@FreeBSD.org> ---
And as a note to myself:

We do
        memcpy(vif->addr, mac, IEEE80211_ADDR_LEN);
in vap_create() but we likely do not synch it again afterwards.  So that could
be the problem.

We likely should re-synch all that state (or what is needed) when coming out of
INIT before going into SCAN (as scan also may depend on that addr).

We should also go and see if we can implement the equivalent of
NL80211_SCAN_FLAG_RANDOM_ADDR which most LinuxKPI based drivers would honor.
