da5dbb9715 iwlagn: set traffic load based on multiple factors
Current BT traffic load should based on the following conditions:

1. BT On/Off status
2. Channel announcement enable/disable
3. Curren traffic load report from uCode

Need to modify rate scale to down-grade from MIMO to SISO if detected
high BT traffic load. Also need to make sure not using chain "B" with high
BT traffic or if it is in "full concurrency" mode.

bee008b783 iwlwifi: add bt full concurrency support
Adding the bluetooth full concurrency support for WiFi/BT combo devices.

Driver should configure uCode to operate in "full concurrency" mode (via
LUT) if both conditions are met:
 - Antenna Coupling is more than 35dB
 - WiFi Channel Inhibition Request is hornored by BT Core

Currently, there is no antenna coupling information provided by uCode;
use module parameter to specified the antenna coupling in dB.

When in "full concurrency" mode, driver need to download different LUT
to uCode while sending bt configuration command; also, driver need to
configure the device operate in 1x1 while in full concurrency mode.

bd6e2d5799 iwlwifi: use antenna A only under high BT load
When bluetooth indicated high load, we should use
only antenna A in 2.4 GHz for management frames.
Add this condition to iwl_toggle_tx_ant() to make
sure it'll always be met. Note that scanning has
a separate way of forcing the antenna, because we
should scan on antenna A only regardless of BT
traffic load.

59079949fa iwlagn: disable gen2b BT coexistence in IBSS
IBSS doesn't allow for coexistence, so it
should be disabled.

Additionally, disable reacting to the BT
profile notification when in IBSS mode,
it likely won't be sent by the device to
start with though.

Also, in IBSS mode, BT coexistence isn't as fully-featured
and we must use a single antenna only. So instead of
peppering the code with new checks, simply pretend
we are in high BT traffic load, which has the needed
effect of disabling antenna B use.

290f599cc6 iwlagn: let bluetooth traffic load impact rate scale
Depending on the amount of bluetooth traffic,
using the shared antenna (antenna B) will have
adverse impact on both bluetooth and wireless
traffic. Add controls to improve the situation
by making rate scaling depend on the BT load.

When there's high bluetooth traffic load, there's
little point in trying to aggregate as BT traffic
would disrupt the aggregated frames all the time,
so simply don't start sessions then.

When BT traffic returns to lower levels, the rate
scaling will come here again automatically when
wifi traffic is high enough, and then it will be
able to successfully enable aggregation.

258086a48b mac80211: cancel restart_work in ieee80211_unregister_hw
Unlike most other workqueue-tasks, the restart_work is
not scheduled onto mac80211's private per-interface
workqueue, but onto one of the system-wide workqueues.

Therefore the mac80211-stack has to cancel any pending
restarts, before destroying the shared device context
and handing back the memory. Otherwise - under very
unlucky circumstances - there could be a stale work-
item left, because some other kernel component might
have delayed the execution of ieee80211_restart_work
for too long.
