Subject: mac80211: Suppress NEW_PEER_CANDIDATE event if no room
From: Masashi Honma <masashi.honma@xxxxxxxxx>
[ Upstream commit 11197d006bcfabf0173a7820a163fcaac420d10e ]
Previously, kernel sends NEW_PEER_CANDIDATE event to user land even if
the found peer does not have any room to accept other peer. This causes
continuous connection trials.
