c30aef01ba iwlwifi: set 512 TX queue slots for AX210 devices
AX210 devices support 256 BA (256 MPDUs in an AMPDU).
The firmware requires that the number of TFDs will be
minimum twice as big as the BA size (2 * 256 = 512).

56fe12d283 iwlwifi: dbg: fill radio registers data regardless of fifos data dumping
The driver calculates memory regions dump size, allocate memory and
fills the data.  The driver fills the radio registers data only if the
memory size of the fifos is greater then zero, so in case the user
masked out the fifos from the dump, the driver will skip filling the
radio register data.

Solve this by checking filling radio registers data independently from
fifos data.

3f7fbc8cc1 iwlwifi: mvm: remove buggy and unnecessary hw_queue initialization
After converting the driver to TXQs, it no longer has any reason
to initialize vif->hw_queue/vif->cab_queue since it no longer sets
the HW_QUEUE_CONTROL flag. Remove the code that initialized those,
it was broken due to relying on an uninitialized stack value in
used_hw_queues, as Colin reported.

192a7e1f73 iwlwifi: mvm: IBSS: use BE FIFO for multicast
Back in commit 4d339989ac ("iwlwifi: mvm: support ibss in dqa mode")
we changed queue selection for IBSS to be:

    if (ieee80211_is_probe_resp(fc) || ieee80211_is_auth(fc) ||
        ieee80211_is_deauth(fc))
            return IWL_MVM_DQA_AP_PROBE_RESP_QUEUE;
    if (info->hw_queue == info->control.vif->cab_queue)
            return info->hw_queue;
    return IWL_MVM_DQA_AP_PROBE_RESP_QUEUE;

Clearly, the thought at the time must've been that mac80211 will
select the hw_queue as the cab_queue, so that we'll return and use
that, where we store the multicast queue for IBSS. This, however,
isn't true because mac80211 doesn't implement powersave for IBSS
and thus selects the normal IBSS interface AC queue (best effort).

This therefore always used the probe response queue, which maps to
the BE FIFO.

In commit cfbc6c4c5b ("iwlwifi: mvm: support mac80211 TXQs model")
we rethought this code, and as a consequence now started mapping the
multicast traffic to the multicast hardware queue since we no longer
relied on mac80211 selecting the queue, doing it ourselves instead.
This queue is mapped to the MCAST FIFO. however, this isn't actually
enabled/controlled by the firmware in IBSS mode because we don't
implement powersave, and frames from this queue can never go out in
this case.

Therefore, we got queue hang reports such as
https://bugzilla.kernel.org/show_bug.cgi?id=201707

Fix this by mapping the multicast queue to the BE FIFO in IBSS so
that all the frames can go out.

07d35b4270 iwlwifi: use sync nmi in case of init flow failure
In case of alive interrupt timeout or any failure in the init flow
the driver generates FW nmi. The driver assumes that the nmi will
generate SW interrupt. This assumption does not hold and leads to faulty
behavior in the recovery flow.

Solve this by using sync nmi, this way, even if the driver does not
receive SW interrupt, it still starts the recovery flow.

Also remove the wait queue from iwl_fwrt_stop_device since the driver is
handling the SW interrupt synchronously.

475c6bde72 iwlwifi: mvm: fix TX crypto on 22560+ devices
In the old days, we could transmit with HW crypto with an arbitrary
key by filling it into TX_CMD. This was broken first with the advent
of CCMP/GCMP-256 keys which don't fit there.

This was broken *again* with the newer TX_CMD format on 22560+,
where we simply cannot pass key material anymore. However, we forgot
to update all the cases when we get a key from mac80211 and don't
program it into the hardware but still return 0 for HW crypto on TX.

In AP mode with WEP, we tried to fix this by programming the keys
separately for each station later, but this ultimately turns out to
be buggy, for example now it leaks memory when we have more than one
WEP key.

Fix this by simply using only SW crypto for WEP in newer devices by
returning -EOPNOTSUPP instead of trying to program WEP keys later.

After the FW image was loaded for the first time,
fwrt->smem_cfg.num_lmacs value will no longer be zero since we don't
clean it when we stop the device. So if we load the image once and then
we fail on a consecutive attempt, the driver will abort any dumping.

when we do the actual dumping in iwl_fw_dbg_collect_sync we check
that STATUS_DEVICE_ENABLED bit is still active.

support by just ignoring 160 MHz on transmit if the peer

the typical case for this workaround is 4x4 AP only doing

8c739d8d79 iwlwifi: mvm: Allow retries for probe responses
When hostapd sends a probe response, it does not request an
acknowledgment on the probe response. This setting is propagated
to the driver and FW from mac80211, and as a result probe responses
are transmitted only once without retries. In congested
environments, this reduces the likelihood for finding the AP.

To overcome this, enable acknowledgment and retries for probe
responses, even in case no acknowledgment is requested. In such
a case the retry limit is set to 3.

6b367c9f88 iwlwifi: nvm-parse: 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 code was detected with the help of Coccinelle.

    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 code was detected with the help of Coccinelle.

e8698301f2 iwlwifi: fix false-positive maybe-uninitialized warning
With CONFIG_NO_AUTO_INLINE, we run into a silly warning when
gcc fails to remember that n_profiles is constant across
the function call to iwl_mvm_sar_set_profile:

drivers/net/wireless/intel/iwlwifi/mvm/fw.c: In function 'iwl_mvm_sar_get_ewrd_table':
drivers/net/wireless/intel/iwlwifi/mvm/fw.c:746:9: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]

Marking that function 'inline' avoids the warning.

99944b7306 iwlwifi: mvm: stop static queues correctly
AP interfaces still use some static TX queues (for probes,
broadcast and multicast frames). These queues were not stopped
correctly when the transport layer indicated the queue should be
stopped. As a result, when flushing the queues, new frames from
the overflow queue were tx'd, so the queues still had frames after
flushing. This ended up in an assert since trying to remove a station
with non-empty queues.

Fix it by stopping the static queues correctly when required.

44135b7c53 iwlwifi: mvm: Do not return an error value on HW restart
When HW restart is requested but not started yet, commands would not
be sent to the FW, and some function calls would return an error. In
case of iwl_mvm_mac_sta_state() returning an error value when a
station is removed can lead to an unneeded warning in
__sta_info_destroy_part2().

Handle this by setting the return value to 0, in case HW restart is
in progress.

When HW restart is requested but not started yet, commands would not

can trigger unneeded warning messages, e.g., in iwl_mvm_mac_sta_state()

Handle a couple of these cases by also checking in the WARN_ON()
condition that HW restart is not requested.

The size of the buffer is IWL_FW_TRIGGER_ID_NUM - 1 which is equal to
IWL_FW_TRIGGER_ID_HOST_CHANNEL_SWITCH_COMPLETE so if the driver receives
this trigger, it will cause a buffer overflow.

Solve this by increasing the buffer size by 1.
