Subject: mac80211: fix software remain-on-channel implementation
From: Johannes Berg <johannes.berg@xxxxxxxxx>
commit 115b943a6ea12656088fa1ff6634c0d30815e55b upstream.
Jouni reported that when doing off-channel transmissions mixed
with on-channel transmissions, the on-channel ones ended up on
the off-channel in some cases.
The reason for that is that during the refactoring of the off-
channel code, I lost the part that stopped all activity and as
a consequence the on-channel frames (including data frames)
were no longer queued but would be transmitted on the temporary
channel.
Fix this by simply restoring the lost activity stop call.
