This is the 3rd edition of the CSA support patch series. This patchset adds generic channel switch support for AP. This is required for DFS operation (e.g. Wi-Fi Alliance requires this for 802.11h certification). This will also be required for IBSS-DFS later. Changes from PATCHv2: * change_channel function for channel context * announce csa support via wiphy flag/cmd * put offset into nested csa information for nl80211 command * various locking, style, documentation and some more minor issues * rebased on latest mac80211-next master The rough design is: * userspace asks kernel to switch a channel using the new NL80211_CMD_CHANNEL_SWITCH command. It supplies IE information for the time while staying on the old channel and announcing the switch, and IE information for after the switch to the new channel. * IE information contains the beacon and optionally probe responses, which should include (E)CSA IEs for the CSA case. Furthermore an offset is provided (for beacon and probe response) to point to the counter field within the channel switch IEs. * The driver gets the new beacons passed and must set them, and decrement the counter field. When it reaches 0, the channel is changed and userspace notified. As always, any comments are appreciated.
