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.
