27bf88829f mac80211: Fixing sparse warning at sta_info.c
The commit 42624d4913
created following sparse warning
>net/mac80211/sta_info.c:965:24: warning: incorrect type in assignment (different address spaces)
>net/mac80211/sta_info.c:965:24:    expected struct tid_ampdu_tx *tid_tx
>net/mac80211/sta_info.c:965:24:    got struct tid_ampdu_tx [noderef] <asn:4>*<noident>

Making use of rcu_dereference_protected to fix the problem.

V2:
 - Replacing rcu_dereference with rcu_dereference_protected
   as suggested by Johannes.
 - Adding mutex_lock/unlock to satisfy the condition at
   rcu_dereference_protected

84381b4ed5 mac80211: split addba retries in time
Currently code allows three (HT_AGG_MAX_RETRIES) unanswered addba
requests. When this limit is reached aggregation is turned off for
given TID permanently. This doesn't seem right: three requests is
not that much, some 'blackout' can happen, but effect of it affects
whole connection indefinitely.
  This patch increases number of retries to 15. Also, when there have
been 3 or more retries it splits further retries apart by 15 seconds
instead of sending them in very short period of time.

79e654787c Bluetooth: Clear RFCOMM session timer when disconnecting last channel
When the last RFCOMM data channel is closed, a timer is normally set
up to disconnect the control channel at a later time.  If the control
channel disconnect command is sent with the timer pending, the timer
needs to be cancelled.

If the timer is not cancelled in this situation, the reference
counting logic for the RFCOMM session does not work correctly when the
remote device closes the L2CAP connection.  The session is freed at
the wrong time, leading to a kernel panic.

When configuring an ERTM or streaming mode connection, remote devices
are expected to send an RFC option in a successful config response.  A
misbehaving remote device might not send an RFC option, and the L2CAP
code should not access uninitialized data in this case.

65983fc7bb Bluetooth: Incoming ACL packets do not force active mode
Incoming sk_buffs always have bt_cb(skb)->force_active set to 0, so
it's misleading to use that value from the control block when calling
hci_conn_enter_active_mode() for incoming data. The destination socket
is not known in the HCI layer, so the force_active setting for each
socket isn't known either. Hard-coding the force_active parameter does
not change any behavior, but makes it obvious that incoming ACL data
never exits sniff mode.
