A new API is coming. This new API is not backward
compatible. So we need to keep the old commands to be able
to work with the former API.
Move all the current code into a new file: coex_legacy.
If a firmware with the new API is detected, we currently
just bail out since the implementation of the new API will
come in future patches.

Introduce new station flag STA_FLG_DISABLE_TX, which is modified with ADD_STA
command. This flag, when set, disables tx to the STA.
Provide an API (iwl_mvm_sta_modify_disable_tx) to modify this flag, which
should be used in channel switch and immediate quiet flows.

Some APs (e.g. TP-LINK TL-WA801N) are disabling aggregation (downlink
to station) when U-APSD is enabled, resulting in low throughput.
Add a module parameter to allow disabling U-APSD support in the driver.
Also re-enable U-APSD for -9 firmware since the firmare issues were
fixed in this release.
There are devices that won't support U-APSD even with newer
firmware, so bring the TLV flag back to detect those.

This patch enables Energy Based Scan (EBS) - intended to detect energy
on 5 GHz band channels. Passive scan on this band takes up to 2.64 sec
assuming 110mSec per-channel * 24 channels. EBS is designed to detect
energy on channels with intensive Wifi activity as well as those where
only beacons are transmitted. EBS completes sampling all channels within
shortest beacon frame transmission time. Total EBS duration is about 100
msec (typical beacon interval).
Detecting Wifi activity on 5 GHz band channels can significantly reduce
scan duration thus saving time and power. EBS failure reported by FW
disables EBS for current connection. It is re-enabled upon new
connection attempt on any WLAN interface.

Today, the driver logic looks for the conditions to disable
power management albeit power management should be enabled
in a very few distinct cases.
This patch changes the driver logic to enable power
management once the required conditions met.
While at it, make some housekeeping and support a few
additional use cases:
a) Add support for a standalone p2p client:
Power management should be enabled for a P2P client
MAC only if the firmware supports it (TLV flag is set).
Instead we used the DCM flag, therefore we didn't cover
use cases that did not include the DCM flag.
b) Add support to Same-Channel-Mode (SCM):
If both clients share the same channel (SCM), and there
are no other active vifs in the system, power management
should be enabled only if the firmware supports this
(TLV flag is set).
c) Fix power management logic for GO/AP:
Today, when we detect an active GO / AP MAC - we disable
power management for all the vifs altogether.
Actually, the correct behavior is to enable power
management on a client if on a different channel
(based on the firmware capabilities).
d) Housekeeping - Along with that, this patch includes some
code-reorganizing: Today the logic of disabling power is
scattered across several functions, specifically in the
iterator. For the sake of both readability and
scalability, we moved this logic to its applicable
function, leaving the iterator gather information only.
Furthermore, as power management is a MAC-related
attribute, we moved the power management member to the
iwl_mvm_vif structure.

We use the TLV flags as a handshake between the firmware
and the driver. These flags allow the firmware to advertise
its capabilities and API version.
Since we are running short of bits, we add a new
infrastructure which is more scalable, yet backward
compatible.
We make now the difference between API changes and the
capabilities. Both can have an index which allows to scale
at will.

New FW enables support for power save on BSS and P2P client MACs
simultaneously when they function on different channels (DCM).
Enable this case in the driver after examining new TLV flag -
IWL_UCODE_TLV_FLAGS_BSS_P2P_PS_DCM. Still power management is not
allowed on both MACs if they function on a same channel.
Remove another redundant TLV flag - IWL_UCODE_TLV_FLAGS_P2P_PS that
is not in use anymore. Remove bound_vif_cnt as redundant.

Use predefined filters, and configure them for
each associated station vif.
There is no need to optimize and attach the same

Newer firmware will support uAPSD clients in AP/GO mode, so complete
the driver support for it. The way it works is described in comments
in the code, but basically the driver just has to pass down all the
mac80211 requests and do accounting on agg/non-agg queues properly.
For older firmware, this doesn't change anything as it ignores the
fields used by the new firmware, and we only advertise uAPSD support
when the firmware does.

FW starts using legacy power table command (0x77) for device wide power
settings. Currently this command contains only option flags field.
It can configure the following: CAM (Continuous Active Mode) and
POWER_SAVE_ENABLE debug option. Send this command when firmware is
loaded - D0 and D3.
Note: Setting this command is important to avoid unwanted FW behavior.
It particularly fixes a bug when a device does not drop to low power
after disassociation from AP.

This is the new API for BT Coex. The full functionality
will be implemented in further patches.
Note: this disables BT Coex for the currently existing
fw (-7 version).
There is also a new command - the channel inhibition command.
This command tells BT what channels to avoid in order to
minimise the interaction between BT and WiFi.
We can tell BT about 2 channels, primary and secondary.
BT will not tune to primary at all and will avoid secondary
as much as possible.
This also means that we need to track vifs that AP / GO.
So rename iwl_mvm_bt_coex_vif_assoc to
iwl_mvm_bt_coex_vif_change to better reflect its real
meaning.
