cfbc6c4c5b iwlwifi: mvm: support mac80211 TXQs model
Move to use the new mac80211 TXQs implementation. This has
quite a few benefits for us. We can get rid of the awkward
mapping of DQA to mac80211 queues. We can stop buffering
traffic while waiting for the queue to be allocated. We can
also use mac80211 AMSDUs instead of building it ourselves.

The usage is pretty simple:
Each ieee80211_txq contains iwl_mvm_txq. There is such a
queue for each TID, and one for management frames. We keep
having static AP queues for probes and non-bufferable MMPDUs,
along with broadcast and multicast queues. Those are being
used from the "old" TX invocation path - iwl_mvm_mac_tx.

When there is a new frame in a TXQ, iwl_mvm_mac_wake_tx is
being called, and either invokes the TX path, or allocates
the queue if it does not exist.

Most of the TX path is left untouched, although we can consider
cleaning it up some more, for example get rid of the duplication
of txq_id in both iwl_mvm_txq and iwl_mvm_dqa_txq_info.

83ea00d687 iwlwifi: mvm: d3: use struct_size() in kzalloc()
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
	int stuff;
        void *entry[];
};

instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);

This issue was detected with the help of Coccinelle.

35739348ba iwlwifi: mvm: clean up SSN incrementation
Sometimes, due to SCD bug, we need to start the queue with an
higher SSN. The queue allocation function currently increments
the SSN in the packet itself, but it is pointless, since this
value is overridden later by iwl_mvm_tx_mpdu with the value
from mvmsta->tid_data[tid].seq_number. Updating tid data is
sufficient.

The FW expects to get the ppe value for each NSS-BW pair in the same
format as in the he phy capabilities IE, which means that a value of 0
implies ppe should be used for BPSK (mcs 0). If there are no PPE
thresholds in the IE, or if for some NSS-RU pair there's no threshold
set for it (this could happen because it's a variable-sized field), it
means no PPE should not be used for that pair, so the value sent to FW
should be 7 which corresponds to "none".

bdf180c8d3 iwlwifi: mvm: change PHY data RX for HE radiotap
The firmware changed the PHY data API, so follow suit.
Some data is now available even for HT/VHT frames, so
the info type in the metadata was changed. This change
isn't backwards compatible, but
 1) the firmware with the old API was never released;
 2) the only overlap in the info type field is from the
    old type of TB to the new of HT, so this basically
    just means that with older FW and newer driver the
    data will be considered missing.

While at it, remove the extra code to set the LTF syms
corresponding to the streams and use the data from the
device instead - we don't really need this in any case
other than when we have it from the device.

As the new API gives use the spatial reuse 1-4 fields
for trigger-based PPDUs, also expose that to radiotap.

When removing the driver, the following flow can happen:
1. host command is in progress, for example at index 68.
2. RX interrupt is received with the response.
3. Before it is processed, the remove flow kicks in, and
   calls iwl_pcie_txq_unmap. The function cleans all DMA,
   and promotes the read pointer to 69.
4. RX thread proceeds with the processing, and is calling
   iwl_pcie_cmdq_reclaim, which will print this error:
   iwl_pcie_cmdq_reclaim: Read index for DMA queue txq id (0),
   index 4 is out of range [0-256] 69 69.

7bc2468277 iwlwifi: mvm: force TCM re-evaluation on TCM resume
When traffic load is not low or low latency is active, TCM schedules
re-evaluation work so in case traffic stops TCM will detect that
traffic load has become low or that low latency is no longer active.
However, if TCM is paused when the re-evaluation work runs, it does
not re-evaluate and the re-evaluation work is no longer scheduled.
As a result, TCM will not indicate that low latency is no longer
active or that traffic load is low when traffic stops.

Fix this by forcing TCM re-evaluation when TCM is resumed in case
low latency is active or traffic load is not low.

the configuration at runtime, after checking the RF ID of the module
installed.  We have a bit of a mess in the code that does this,
because it applies cfg's according to the RF ID only, ignoring the
integrated module that is in use.

Fix that for some devices by adding correct configurations for them
and not ignoring the integrated module's type when making the
decision.

82715ac71e iwlwifi: mvm: fix regulatory domain update when the firmware starts
When the firmware starts, it doesn't have any regulatory
information, hence it uses the world wide limitations. The
driver can feed the firmware with previous knowledge that
was kept in the driver, but the firmware may still not
update its internal tables.

This happens when we start a BSS interface, and then the
firmware can change the regulatory tables based on our
location and it'll use more lenient, location specific
rules. Then, if the firmware is shut down (when the
interface is brought down), and then an AP interface is
created, the firmware will forget the country specific
rules.

The host will think that we are in a certain country that
may allow channels and will try to teach the firmware about
our location, but the firmware may still not allow to drop
the world wide limitations and apply country specific rules
because it was just re-started.

In this case, the firmware will reply with MCC_RESP_ILLEGAL
to the MCC_UPDATE_CMD. In that case, iwlwifi needs to let
the upper layers (cfg80211 / hostapd) know that the channel
list they know about has been updated.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=201105

8954e1eb22 iwlwifi: trans: Clear persistence bit when starting the FW
In D3 suspend flow in 9260 gen2 HW, the NIC receives two PERST signals.
The first PERST is expected and indicates the device on coming resume flow.
The second PERST causes FW restart FW restart.
In order to avoid this issue, the FW set the persistence bit on.
Once this bit is set, the FW ignores reset attempts.
The problem is when the FW gets assert during D3 and then the persistence
bit is set and causes the FW to ignore reset.
To handle this issue, the FW opens the preg bit which allows access
to the persistence bit, so that the driver clear the persistence bit
and reset the NIC.

The flow is as follows:
the driver checks if the persistence bit is set.
If the bit is set, the driver checks if he can clear the bit.
If the driver can not clear the bit then there is no point to continue
configuring the NIC since it will fail.

The fix was added is in start HW flow instead of the resume flow since in
general, if the persistence bit is set, the driver can not start the FW.
So it is good to check it when we start configuring the NIC.

The driver does not need to close the preg bit since the FW close it
during the start flow.

724fe7710a iwlwifi: mvm: kill INACTIVE queue state
We don't really need this state: instead of having an inactive
state where we can awaken zombie queues again if needed, just
keep them in their normal state unless a new queue is actually
needed and there's no other way of getting one.

We do this here by making the inactivity check not free queues
unless instructed that we now really need to allocate one to a
specific station, and in that case it'll just free the queue
immediately, without doing any inactivity step inbetween.

The only downside is a little bit more processing in this case,
but the code complexity is lower.

Additionally, this fixes a corner case: due to the way the code
worked, we could only ever reuse an inactive queue if it was
the reserved queue for a station, as iwl_mvm_find_free_queue()
would never consider returning an inactive queue.

4244e7fc70 iwlwifi: dump debug data before stop device
Debug data dump is not working in flows that stop the device is used
in their error handling. During these flows the op mode mutex is
locked until the device stops.  Because of that, any assert generated
from the firmware can be handled only after the device already
stopped.

Since dumping cannot occour after stopping the device, split the the
dump function to two parts, Part that handles locking, and the part
that starts the actual dumping and call the second part in the op mode
stop device function.

2ec3ef4614 iwlwifi: mvm: use fast balance scan in case of DCM mode with P2P GO
Currently in case of DCM with P2P GO where BSS DTIM interval < 220 msec
the fw fails to allocate events for the P2P GO dtim due to long passive
scan events.

Fix this by requesting all scans in this scenario to be fragmented with
fast balance scan time settings.  The only exception is in case
fragmented scan was planned to be set due to low latency or high
throughput reason, set the scan timing as planned.

868a1e863f iwlwifi: pcie: avoid empty free RB queue
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

155f7e0441 iwlwifi: mvm: clear HW_RESTART_REQUESTED when stopping the interface
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:

drivers/net/wireless/intel/iwlwifi/pcie/trans.c:2122 iwl_trans_pcie_grab_nic_access+0xc0/0x1d6 [iwlwifi]()

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:

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

79f25b10c9 iwlwifi: dbg: don't crash if the firmware crashes in the middle of a debug dump
We can dump data from the firmware either when it crashes,
or when the firmware is alive.
Not all the data is available if the firmware is running
(like the Tx / Rx FIFOs which are available only when the
firmware is halted), so we first check that the firmware
is alive to compute the required size for the dump and then
fill the buffer with the data.

When we allocate the buffer, we test the STATUS_FW_ERROR
bit to check if the firmware is alive or not. This bit
can be changed during the course of the dump since it is
modified in the interrupt handler.

We hit a case where we allocate the buffer while the
firmware is sill working, and while we start to fill the
buffer, the firmware crashes. Then we test STATUS_FW_ERROR
again and decide to fill the buffer with data like the
FIFOs even if no room was allocated for this data in the
buffer. This means that we overflow the buffer that was
allocated leading to memory corruption.

To fix this, test the STATUS_FW_ERROR bit only once and
rely on local variables to check if we should dump fifos
or other firmware components.

1. iwl_fw_get_prph_len - returns the size needed for periphery dump.
2. iwl_fw_dump_mem for - executes the memory dumping flow.
3. iwl_trans_get_fw_monitor_len - returns the size needed for monitor dump.

5cfe79c8d9 iwlwifi: fw: stop and start debugging using host command
In new devices, access to periphery is forbidden. Send instead
host command to start and stop debugging.

Memory allocation is written in context info, but in case we
need to update it there is a dedicated command. Add definitions,
currently unused, of the new command.

d25eec305c iwlwifi: fw: add a restart FW debug function
Move the restart FW debug code to a function. This avoids code
duplication and lays the infra to support the new start and stop
host commands in some future devices.

7eff513674 iwlwifi: mvm: fix a comment about the SP length
The SP length in the ADD_STA command is an actual number of
frames, and not the SP len as it appears in the WME IE.
Fix that comment. The actual code is fine.
