When a station is removed, its statistics may be interesting to userspace, for example for further aggregation of statistics of all stations that ever connected to an AP. Introduce a new cfg80211_del_sta_sinfo() function (and make the cfg80211_del_sta() a static inline calling it) to allow passing a struct station_info along with this, and send the data in the nl80211 event message.

Add a new regulatory flag that allows a driver to manage regdomain changes/updates for its own wiphy. A self-managed wiphys only employs regulatory information obtained from the FW and driver and does not use other cfg80211 sources like beacon-hints, country-code IEs and hints from other devices on the same system. Conversely, a self-managed wiphy does not share its regulatory hints with other devices in the system. If a system contains several devices, one or more of which are self-managed, there might be contradictory regulatory settings between them. Usage of flag is generally discouraged. Only use it if the FW/driver is incompatible with non-locally originated hints. A new API lets the driver send a complete regdomain, to be applied on its wiphy only. After a wiphy-specific regdomain change takes place, usermode will get a new type of change notification. The regulatory core also takes care enforce regulatory restrictions, in case some interfaces are on forbidden channels.

Add a new NL80211_CH_SWITCH_STARTED_NOTIFY message that can be sent to the userspace when a channel switch process has started. This allows userspace to take action, for instance, by requesting other interfaces to switch channel as necessary. This patch introduces a function that allows the drivers to send this notification. It should be used when the driver starts processing a channel switch initiated by a remote device (eg. when a STA receives a CSA from the AP) and when it successfully starts a userspace-triggered channel switch (eg. when hostapd triggers a channel swith in the AP).

A mandatory parameters during the ocb_join operation are 'center frequency' and 'channel width (5/10 MHz)'.

During the review of the corresponding wpa_supplicant patches we noticed that the only way for it to detect that this functionality is supported currently is to check for the command support. This can be misleading though, as the command was also designed to, in the future, support pure 802.11 TSPECs. Expose the WMM-TSPEC feature flag to nl80211 so later we can also expose an 802.11-TSPEC feature flag (if needed) to differentiate the two cases. Note: this change isn't needed in 3.18 as there's no driver there yet that supports the functionality at all. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>
