From 47edb11b522561658fe719e56aa69a3c3098a3fe Mon Sep 17 00:00:00 2001 From: Ayala Beker Date: Mon, 21 Sep 2015 15:49:53 +0300 Subject: cfg80211: allow changing station capabilities for unassociated stations Currently, cfg80211 rejects capability updates for existing entries and as a result it's impossible to update entries that were added unassociated, but that is necessary to go through the full station states from userspace, adding a station before authentication etc. Fix this by allowing updates to capabilities for stations that the driver (or mac80211) assigned unassociated state. Drivers setting the full station state support flag must use the new station type for proper operation.
