it depends what you're trying to do.
Are you trying to dynamically change channel based on channel usage? Then you can just look at mac80211; it already knows how to change channels. It'll just call the driver to change the channel as appropriate. You don't need to necessarily modify ath9k to do it.


Are you trying to do some kind of synthetic, slow frequency hopping? (eg with quick channel changes?) Then that's a different story.

Hey Adrian and people,

C'mon please suggest me which function/files will help me modify channel hopping functionality in ath9k driver?

Thanks!

I thought Adrian's answer was concise and to the point. ?That said, here's some pseudo code:
. make a decision which yields the next operating frequency
. stuff it in mac80211 or thereabouts. prn until you get it right!?End of story.

Exactly Larry,

It was too to the point. I am sorry but I do not have much knowledge about kernel programming and I do not know which functions in the file will change it. I do not know where should I stuff it in mac80211 or inside ath9k files. I tried doing it in some of the existing files but i do not know their basis. No matter where I do, the channel is picked up from the hostapd. Kindly be a little more detailed.

Thank you so much for your time!
