How do you plan to merge CRDA and Country IE When a Country IE is received and parsed in mac80211 its up to mac80211 then to decide what to do. As per the specification you should use what the AP sends in the country IE but from what I am seeing vendors tend to do different things with the Country IE. Some considerations against parsing the Country IE and trusting it completely is concerns about "rogue" APs. So as a compromise I was thinking that initially we can simply call CRDA with the alpha2 passed in the Country IE. Then later we can have it actually get the intersection between what the AP provides and what CRDA has. The driver will *always* have the ultimate say though through the callback if it is registered. The callback will usually be used by vendor drivers who have more stringent requirements on their regulatory considerations. In the end though if trust is built around the data CRDA provides it should be more than enough. Now these are just my observations so far. Please feel free to chime in if there are better alternatives. We probably should take some time to talk about this at OLS but for now that's what I'm aiming for. > where you will keep > Country IE info cfg80211 or mac80211? That belongs in mac80211. You only need to tell cfg80211 the alpha2 so it can query CRDA for you.
