cfg80211_notify_new_candidate - notify cfg80211 of a new mesh peer candidate

: network device : the MAC address of the new candidate : information elements advertised by the peer candidate : lenght of the information elements buffer : allocation flags

This function notifies cfg80211 that the mesh peer candidate has been detected, most likely via a beacon or, less likely, via a probe response. cfg80211 then sends a notification to userspace.
