Hello Johannes and all,

Here is a patch set with minor cleanups/updates needed to enable
DFS offload in cfg80211. 

Note that the third patch enables DFS offload for qtnfmac driver.
We assume that it should go through wireless-drivers tree after
all cfg80211/nl80211 changes are reviewed and merged. So it is
posted here for reference purposes only.

Besides, minimal set of user-space changes for hostapd has been
already posted to hostapd mailing list.

Thanks,
Sergey
