Thanks a lot for the rewrite - looks good to me and works well here, so
feel free to add:

Tested-by: Simon Wunderlich <siwu at hrz.tu-chemnitz.de>

Also the patch looks good in general. This series is still missing the
dfs channel list patch which is in another patch Jouni has still backed
up [1] (doesn't apply currently, but it's trivial to fix). Would be good
to merge this as well.

Just one remark: What do we do if all channels are taken? Your current
implementation will then simply close hostapd, but I'm not sure if this
is desired behaviour - shouldn't we rather keep it running and wait for one
channel to come back (when the Non-occupancy-period is over) and try again?

Cheers and thanks,
