Emmanuel Grumbach 2b76ef1308 iwlwifi: mvm: implement reduced Tx power
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.

Emmanuel Grumbach e3d9e7ce4c iwlwifi: mvm: support IEEE80211_AMPDU_TX_STOP_FLUSH
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.

Emmanuel Grumbach 410dc5aa59 iwlwifi: a few fixes in license
7000.c was released as GPL only by mistake: it should be
dual licensed - GPL / BSD.
The file that contains the license in the kernel is COPYING
and not LICENSE.GPL.

Johannes Berg 9cc40712a0 iwlwifi: mvm: fix GO powersave client manipulation
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.

Johannes Berg 7a4539736e iwlwifi: mvm: update station when marked associated
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.

Johannes Berg 8ca151b568 iwlwifi: add the MVM driver
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.
