Hi,

this is not good, if alternate MACs are not supported, because you also
need them to configure multiple access points in hostapd. Take a look
at the end of the hostapd.conf in examples. This definitely takes away
features.

Like I said... the ath(4) driver is dropping/blocking/filtering the
packets somewhere in the send code. The receive part and the network
operation generally work correctly, as far as I can remember.

I'll take a look at it soon.
