Beacons from external BSSes are required for updating overlapping BSS
info (i.e. ERP protection). Pass them up unconditionally.

In src/ap/ap_list.c (hostap.git) ;-)
This code has been there for a long time, but the functionality was
broken at some point (maybe already during d80211 -> mac80211 process)
due to the beacons not getting delivered there anymore.

Oh, I guess then they are delivered via the monitor interface?

I haven't tested this patch, but yes, I would assume so. They used to be
delivered in the exact same way as other management frames and at this
point, that would indeed be the monitor interface.
