I have now changed it but I personally think that this will not work. Many
filters/firewalls go crazy when they see zero mac addresses, the first bcast
batadv_is_my_mac check is not working anymore and it should not be possible to
send over IBSS or Sta-to-AP with a zero mac source address. From AP-to-Sta is
not a problem because it can use 4 addresses in its header. But the other way
around is problematic because only 3 address are in the wifi header. A
transfer with zero mac address as source address from Sta-to-AP with ath9k/
mac80211 should end up in an Ack back to 00:00:00:00:00:00 and a
deauthentication frame to 00:00:00:00:00:00.
Kind regards,
Sven
