Use beacon statistics notification to track RSSI.
Notify mac80211 when the tresholds are crossed.
The roaming treshold is configured to be
equal to cqm_thold. If the beacon filtering command
is not supported by fw fall back and use mac80211
mechanism.

Change power management implementation to support new host-device API
containing uAPSD parameters. Verify FW support for this new API.
Use the new power table command (0xA9) to configure power management.
Use the legacy command (0x77) if FW does not support the new API.
New file power_legacy.c is introduced for legacy implementation.

The firmware supports periodic keep alive and beacon monitoring,
so advertise connection monitor offload capability by setting
IEEE80211_HW_CONNECTION_MONITOR flag. Implement missed beacons
notification handler. Call ieee80211_beacon_loss in case of
missed beacons, so AP probing by mac80211 can be triggered.

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.

Without this command, the firmware will filter out all the
multicast frames. Let them all in as for now. Later we will
want to optimize this to save power.

The FW scheduler, schedules the bindings over a session of 128
fragments (each is 4 TU long). The quota command should allocate
all the session fragments between all the bindings that require quota
allocation. Currently, use static allocation, where the fragments
are equally distributed between all data bindings.

Note, that not allocating all the session's fragments might cause
the FW scheduler to leave the medium unused.

Newer firmware revisions have a completely new

new API.

I've listed the people who directly contributed
code, but many others from various teams have
contributed in other ways.
