mac80211: Add debugfs callbacks for station addition/removal
Provide drivers with hooks to create debugfs files when a new station is added. This would help drivers to take advantage of mac80211's station list infrastructure and not maintain tedious station management code internally. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> [ifdef inline wrapper functions] Signed-off-by: Johannes Berg <johannes.berg@intel.com>
