A separate SCD queue is mapped to this fifo - the cab_queue

According to the FW implementation, the quota command should
have a valid entry for each active binding (where 'active' in
this context means that the binding is known to the FW). In case
the binding should not get any quota, the 'quota' should be set
to zero.
Not setting an 0 quota for an active binding when all the MACs
in the binding are idle, i.e., not associated in case of managed
interface, will result in preventing the FW scheduler from entering
IDLE state and the FW from transitioning to low PS.

For testing the D3 (WoWLAN) firmware, it is useful to be able
to run the firmware with instrumentation while the host isn't
sleeping and can poke at the firmware debug logging etc.
Implement this by a debugfs file. When the file is opened the
D3 firmware is loaded and all regular commands are blocked.
While the file is being read, poll the firmware's PME status
flag and report EOF once it changes to non-zero. When it is
closed, do (most of) the resume processing. This lets a user
just "cat" the file. Pressing Ctrl-C to kill the cat process
will resume the firwmare as though the platform resumed for
non-wireless reason and when the firmware wants to wake up
reading from the file automatically completes.
Unlike in real suspend, only disable interrupts and don't
reset the TX/RX hardware while in the test mode. This is a
workaround for some interrupt problems that happen only when
the PCIe link isn't fully reset (presumably by changing the
PCI config space registers which the core PCI code does.)
Note that while regular operations are blocked from sending
commands to the firmware, they could still be made and cause
strange mac80211 issues. Therefore, while using this testing
feature you need to be careful to not try to disconnect, roam
or similar, and will see warnings for such attempts.
Als note that this requires an upcoming firmware change to
tell the driver the location of the PME status flag in SRAM.
D3 test will fail if the firmware doesn't report the pointer.

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.
