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.

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.

Fix this by moving the clearing of the flags to exactly where we learn about the situation. This creates a problem of reordering, so introduce another flag indicating that delivery is being done, this new flag also queues frames and is cleared only while the spinlock is held (which the queuing code also holds) so that any concurrent delivery/TX is handled correctly.
