By storing a shift value for all duration values of a group, we can
reduce precision by a neglegible amount to make it fit into a u16 value.
This improves cache footprint and reduces size:

I'm not really sure exactly _why_ I've been carrying a note
for what's probably _years_ to check that we don't do this,
but we clearly do reflect frames back to the station itself
if it sends such.
One way or the other, it's useless since the station doesn't
really need the AP to talk to itself, so suppress it.
While at it, clarify some of the logic by removing skb->data
references in favour of the destination address (pointer) we
already have separately.

addresses was not added to the API. This caused the driver to assume
there is only one address which results in all interfaces getting the

If all free RB queues are empty, the driver will never restock the
free RB queue. That's because the restocking happens in the Rx flow,
and if the free queue is empty there will be no Rx.
Although there's a background worker (a.k.a. allocator) allocating
memory for RBs so that the Rx handler can restock them, the worker may
run only after the free queue has become empty (and then it is too
late for restocking as explained above).
There is a solution for that called 'emergency': If the number of used
RB's reaches half the amount of all RB's, the Rx handler will not wait
for the allocator but immediately allocate memory for the used RB's
and restock the free queue.
But, since the used RB's is per queue, it may happen that the used
RB's are spread between the queues such that the emergency check will
fail for each of the queues
(and still run out of RBs, causing the above symptom).
To fix it, move to emergency mode if the sum of *all* used RBs (for
all Rx queues) reaches half the amount of all RB's

Fix a bug that happens in the following scenario:
1) suspend without WoWLAN
2) mac80211 calls drv_stop because of the suspend
3) __iwl_mvm_mac_stop deallocates the aux station
4) during drv_stop the firmware crashes
5) iwlmvm:
* sets IWL_MVM_STATUS_HW_RESTART_REQUESTED
* asks mac80211 to kick the restart flow
6) mac80211 puts the restart worker into a freezable
queue which means that the worker will not run for now
since the workqueue is already frozen
7) ...
8) resume
9) mac80211 runs ieee80211_reconfig as part of the resume
10) mac80211 detects that a restart flow has been requested
and that we are now resuming from suspend and cancels
the restart worker
11) mac80211 calls drv_start()
12) __iwl_mvm_mac_start checks that IWL_MVM_STATUS_HW_RESTART_REQUESTED
clears it, sets IWL_MVM_STATUS_IN_HW_RESTART and calls
iwl_mvm_restart_cleanup()
13) iwl_fw_error_dump gets called and accesses the device
to get debug data
14) iwl_mvm_up adds the aux station
15) iwl_mvm_add_aux_sta() allocates an internal station for
the aux station
16) iwl_mvm_allocate_int_sta() tests IWL_MVM_STATUS_IN_HW_RESTART
and doesn't really allocate a station ID for the aux
station
17) a new queue is added for the aux station
Note that steps from 5 to 9 aren't really part of the
problem but were described for the sake of completeness.
Once the iwl_mvm_mac_stop() is called, the device is not
accessible, meaning that step 12) can't succeed and we'll
see the following:

The station id of the aux station is set to 0xff in step 3
and because we don't really allocate a new station id for
the auxliary station (as explained in 16), we end up sending
a command to the firmware asking to connect the queue
to station id 0xff. This makes the firmware crash with the
following information:
0x00002093 | ADVANCED_SYSASSERT
0x000002F0 | trm_hw_status0
0x00000000 | trm_hw_status1

Firmware error during reconfiguration - reprobe!
FW error in SYNC CMD SCD_QUEUE_CFG
Fix this by clearing IWL_MVM_STATUS_HW_RESTART_REQUESTED
in iwl_mvm_mac_stop(). We won't be able to collect debug
data anyway and when we will brought up again, we will
have a clean state from the firmware perspective.
Since we won't have IWL_MVM_STATUS_IN_HW_RESTART set in
step 12) we won't get to the 2093 ASSERT either.

Allow the FW to reorder HB channels and first scan HB channels with
assumed APs, in order to reduce the scan duration.

Split iwl_fw_error_dump to two parts. The first part will dump the
actual data, and second will do the file allocations, trans calls and
actual file operations. This is done in order to enable reuse of the
code for the new debug ini infrastructure.
