+    mac80211: set new interfaces as idle upon init
+    
+    Mark new interfaces as idle to allow operations that require that
+    interfaces are idle to take place. Interface types that are always
+    not idle (like AP interfaces) will be set as not idle when they are
+    assigned a channel context.

+    mac80211: fix virtual monitor interface addition

+    Since the commit below, cfg80211_chandef_dfs_required()
+    will warn if it gets a an NL80211_IFTYPE_UNSPECIFIED iftype
+    as explicitely written in the commit log.
+    When an virtual monitor interface is added, its type is set
+    in ieee80211_sub_if_data.vif.type, but not in
+    ieee80211_sub_if_data.wdev.iftype which is passed to
+    cfg80211_chandef_dfs_required() hence resulting in the
+    following warning:

+
+    mac80211: use csa counter offsets instead of csa_active
+    
+    vif->csa_active is protected by mutexes only. This
+    means it is unreliable to depend on it on codeflow
+    in non-sleepable beacon and CSA code. There was no
+    guarantee to have vif->csa_active update be
+    visible before beacons are updated on SMP systems.
+    
+    Using csa counter offsets which are embedded in
+    beacon struct (and thus are protected with single
+    RCU assignment) is much safer.

+    mac80211: move csa counters from sdata to beacon/presp
+    
+    Having csa counters part of beacon and probe_resp
+    structures makes it easier to get rid of possible
+    races between setting a beacon and updating
+    counters on SMP systems by guaranteeing counters
+    are always consistent against given beacon struct.
+    
+    While at it relax WARN_ON into WARN_ON_ONCE to

+    cfg80211: make ethtool the driver's responsibility
+    
+    Currently, cfg80211 tries to implement ethtool, but that doesn't
+    really scale well, with all the different operations. Make the
+    lower-level driver responsible for it, which currently only has
+    an effect on mac80211. It will similarly not scale well at that
+    level though, since mac80211 also has many drivers.
+    
+    To cleanly implement this in mac80211, introduce a new file and
+    move some code to appropriate places.
