Hi, Some AP's use local operating class in (E)CSA IE's. Currently mac80211 fails the parsing of those IE's and results in a disconnection. What is the best way to add support for local operating classes? a) Maintaining a per country operating class table in cfg80211 b) Embed operating class info in regdb.txt (crda) c) Remove the usage of band to calculate frequency? I dont know of a generic formula to calculate this across bands. So not possible. -- Thanks, Regards, Chaitanya T K.
