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.
Thanks & regards,
Srinivasan

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
Hi Simon,
