+ 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.

+ will warn if it gets a an NL80211_IFTYPE_UNSPECIFIED iftype

+ When an virtual monitor interface is added, its type is set

+ 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.

+ The channel_switch_beacon callback is optional, so it doesn't have to
