From 7e927748d4db4d248e919e44f4dd4891ba6b4d42 Mon Sep 17 00:00:00 2001 From: Masashi Honma Date: Wed, 30 Nov 2016 09:06:04 +0900 Subject: mac80211: Suppress NEW_PEER_CANDIDATE event if no room [ 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.
