In the regular flow, when we receive an assert, ieee80211_reconfig is
called which reconfig the driver using iwl_mvm_mac_start.
iwl_mvm_mac_start is clearing the restart bit and does dump collection.
Prior to setting the device up, ieee80211_reconfig does not call
iwl_mvm_mac_start since there is nothing to reconfig and we miss the
dump collection of the assert.
solve it by checking the restart bit before we stop the device
and trigger a dump collection in case it is set.
note that we don't need to do it in the fmac case since in fmac

TX path lock was introduced in order to prevent out of order
invocations of TX.
This can happen in the following flow:
TX path invoked from net dev
Packet dequeued
TX path invoked from RX path
Packet dequeued
Packet TXed
Packet TXed
However, we don't really need a lock. If TX path is already
invoked from some location, other paths can simply abort their
execution, instead of waiting to the first path to finish, and
then discover queue is (likely) empty or stopped.
Replace the lock with an atomic variable to track TX ownership.
This simplifies the locking dependencies between RX and TX paths,
and should improve performance.

Clean up the LDBG config command to not be called "continuous

recording implementation completely since it was only used for
store & forward architectures.
This also fixes a bug at least in iwl_fw_dbg_buffer_allocation()
because what's now "__le32 type" (matching the firmware) used to
be "__le16 enable_recording", so the buffer allocation config
sub-struct would erroneously have started at the wrong offset.
In the other cases this didn't actually lead to a bug as other
bytes in pad[] were all zeroes, so accessing the 16-bit value as
a 32-bit value wouldn't make a difference (in little endian.)

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.

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.

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".

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

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.

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 new debug ini TLVs can be either packed into firmware
binary or written in external file. Support loading them
from both. Store the data per apply point. Apply point is
a point during driver runtime, where the TLV becomes active.
For example, a trigger of hardware error may be configured
to collect a subset of data pre-alive, as a opposed to HW
error that occurs after alive.

We have to choose different configuration and different firmwares
depending on the external RF module that is installed. Since the
external module is not represented in the PCI IDs, we need to change
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.

We can't use SAR Geo if basic SAR is not enabled, since the SAR Geo
tables define offsets in relation to the basic SAR table in use.
To fix this, make iwl_mvm_sar_init() return one in case WRDS is not
available, so we can skip reading WGDS entirely.

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.

When read the ACPI data to find out the WGDS, the DATA_SIZE is never
matched.
From the above format, it gives 19 numbers, but our driver is hardcode
as 18.
Fix it to pass then can parse the data into our wgds table.

TDLS discovery response frame is a unicast direct frame to the peer.
Since we don't have a STA for this peer, this frame goes through
iwl_tx_skb_non_sta(). As the result aux_sta and some completely
arbitrary queue would be selected for this frame, resulting in a queue
hang. Fix that by sending such frames through AP sta instead.

FW asserts 0x70, 0x71, and 0x73 all just mean that the real error
happened in another MAC, and to look there for the problem. Add their
descriptions to the assert number lookup table so users get a nicer
error message in the logs.
Also, since the 4 most-significant bits of the assert number are
dynamic, and depend on which MAC the assert occurred on, ignore those
bits when looking up the assert name.
