Please CC linux wireless when posting queries on cfg/mac80211.

At least, I have not had any issues in interface bring up after the latest regulatory.db change, I have tested it with vanilla ath.git and it worked even without regulatory.db file.
If you may want to refer, Johannes submitted a patch[1] for converting db.txt to firmware file format.
