The fw recently added an option to set tx power reduction
per station (in the lq_cmd command), and get the tx power
reduction used (in the tx_resp struct).
Use them and propogate this value up to mac80211's tx
response (in order to use it later in the rate-scaling
algorithm).

The d3/d0i3 fw code requires the sta_id to be 0
(this is used to determine the rates and keys
to use in arp offloading).
Reserve sta_id 0 to station interface in order
to comply with this requirement.
Change some functions prototypes in order to
make the allocation function know about
the interface type.

This will be useful during tests done on the physical layer.

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.

This is just a helper function to go from the mac80211
station struct to our internal one, to later allow us
to avoid temporary 'mvmsta' variables.

Instead of keeping track of the non-QoS seqno for each station,
query the firmware when suspending, that's more efficient. As
this can fail, move the station ID mangling later in the code.

In order to avoid NIC destruction due to high temperature,
CT kill will power down the NIC.
To avoid this, thermal throttling will decrease throughput
to prevent the NIC from reaching the temperature at which
CT kill is performed.

Move the counter for non-AMPDU frames to mvm. It is needed
for the drain flow which happens once the ieee80211_sta has
been freed, so keeping it in iwl_mvm_sta which is embed into
ieee80211_sta is not a good idea.
Also, since its purpose it to remove the STA in the fw only
after all the frames for this station have exited the shared
Tx queues, we need to decrement it in the reclaim flow. This
flow can happen after ieee80211_sta has been removed, which
means that we have no iwl_mvm_sta there. So we can't know
what is the vif type. Hence, we know audit these frames for
all the vif types.
In order to avoid spawning sta_drained_wk all the time, we
now check that we are in a flow in which draining might
happen - only when mvmsta is NULL. This is better than
previous code that would spawn sta_drained_wk all the time
in AP mode.

This allows to have better wifi TPT when BT is active under
good RSSI conditions.
Wifi will have better chance to send Acks and Cts even if BT
is active.

mac80211 tells us when we need to dump the frames from the
AGG queue instead of releasing them as single MPDUs.
Being able to differentiate between the different cases
(IEEE80211_AMPDU_TX_STOP_*) allows us to handle races better.
When the station is removed, mac80211 asks to flush and
removes the station right away.
This allows to avoid a case where we still have frames in
AGG queues, but the station has been remove already.
Note that we can have frames on the shared queues, but this
is not a problem: the station in the fw will be kept until
all the frames on the shared queues have been drained.
AGG queues are a special case since they are dynamically
allocated.

All station commands must include a valid MAC ID,
the ID 0 is randomly valid in some cases, but we
must set the ID properly. Do that by passing the
right station and using its mac_id_n_color.

In managed mode, the HT/VHT capabilities aren't set when
the station is initially added, so update the station
when it is marked associated. In AP/GO mode, the station
will typically be added with full capabilities today,
but an upcoming change in hostapd may mean a similar
scenario as for managed mode, therefore do the update
unconditionally.

Newer firmware revisions have a completely new
firmware API. This is the new driver for this
new API.
I've listed the people who directly contributed
code, but many others from various teams have
contributed in other ways.
