From: Johannes Berg <johannes.b...@intel.com>
There's nothing much for mac80211 to do, so only pass through
the requests with minimal checks and tracing. The driver must
call cfg80211's results APIs.
Signed-off-by: Johannes Berg <johannes.b...@intel.com>

v4: first version - just takes the same number as the cfg80211 patch
v5: no changes
v6: no changes
v7: no changes
