Since cfg80211 will now call the explicit stop_ap operation when an AP interface goes down, move all teardown code there and remove it from interface handling. The only thing that needs to stay is the code to dev_close() all dependent VLANs. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

This patch prepares mac80211 for a later implementation of mesh or ad-hoc powersave clients. The structures related to powersave (buffer, TIM map, counters) are moved from the AP-specific interface structure to a generic structure that can be embedded into any interface type. The functions related to powersave are prepared to allow easy extension with different interface types. For example with: + } else if (sta->sdata->vif.type == NL80211_IFTYPE_MESH_POINT) { + ps = &sdata->u.mesh.ps; Some references to the AP's beacon structure are removed where they were obviously not used. The patch compiles without warning and has been briefly tested as AP interface with one client in PS mode.

If the user wants to scan using a vif configured as AP, cfg80211 must give him a chance to do it, even if this will disrupt the stations performance due to off-channel scanning. To do so, this patch adds a 'force' flag to the SCAN_TRIGGER command which tells cfg80211 to perform the scanning operation even if the vif is an AP and the beaconing has already started.

Add an NL80211_SCAN_FLAG_FLUSH flag that causes old bss cache entries to be flushed on scan completion. This is useful for collecting guaranteed fresh scan/survey result (e.g. on resume). For normal scan, flushing only happens on successful completion of a scan; i.e. it does not happen if the scan is aborted. For scheduled scan, previous scan results are flushed everytime when we get new scan results. This feature is enabled by default. Drivers can disable it by unsetting the NL80211_FEATURE_SCAN_FLUSH flag.

The next patch will introduce a flag that is set by default in cfg80211 so drivers and mac80211 need to use |= to set features they have so that they don't clear the already-set feature. We could set the flag in wiphy_register() instead of wiphy_new() to avoid this patch, but then the drivers couldn't *unset* flags they don't want to use even though the implementation is generic.

On each channel that the device is operating on, it may need to listen using one or more chains depending on the SMPS settings of the interfaces using it. The previous channel context changes completely removed this ability (before, it was available as the SMPS mode). Add per-context tracking of the required static and dynamic RX chains and notify the driver on changes. To achieve this, track the chains and SMPS mode used on each virtual interface and update the channel context whenever this changes. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>
