802.11h DFS support

Hi,
I was looking for the DFS support in
mac80211/cfg80211/nl80211/hostapd and observed that the latest wireless-testing kernel & hostapd.git does not include support for 802.11h.

I also referred few patches submitted by Victor Goldenshtein
which had support for entire DFS operation basing wireless-testing kernel. As per my understanding these patches are presently getting modified to support new channel-context modifications.

Could someone confirm if I am right at my understanding.

Yup. Actually I picked up Victors patchset and doing the channel context rework right now, and plan to send a revised patchset for nl80211/mac80211 soon.

"Entire" DFS operation is not entirely correct. There will still be quite a few bits missing:

* driver support - some drivers like ath9k have something prepared, but it still needs to be integrated
* ETSI/FCC support has to be verified for the different drivers
* testing, of course

Cheers,
Simon
