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,
