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.
that's correct.
         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
