Subject: iwlwifi: mvm: disconnect in case of bad channel switch parameters

In case we receive channel switch announcement with immediate
quiet and unknown switching time, we will switch when FW identifies
AP left channel. However, if AP remains on channel, we will
eventually get TX queue hang. Init a work to disconnect if
switch doesn't occur within 1500 milliseconds. Do it also
for a too long channel switch.

Subject: iwlwifi: mvm: track changes in beacon count during channel switch

There are some buggy APs that keeps changing the count while forcing
us to block TX. This eventually results in queue hang, assert, and
disconnection. Detect such APs and disconnect gracefully in advance.

Subject: iwlwifi: mvm: be more forgiving if num of channels is too big

If number of channels in the driver is greater than
number of scan channels given by firmware TLV, do not
fail scan config, but adjust to firmware's number of channels.
This is helpful for supporting in driver new channels before
it being supported by firmware scan.

Subject: iwlwifi: mvm: Support new format of SCAN_OFFLOAD_PROFILES_QUERY_RSP

Newer FWs use a new format of the SCAN_OFFLOAD_PROFILES_QUERY_RSP,
which now supports indicating match on an higher number of channels.

Modify the code to support both the old format and the newer one,
based on a FW TLV.

Subject: iwlwifi: mvm: use dump worker during restart instead of sync dump

In restart flow, the driver requests HW restart from mac80211
and then mac80211 uses a worker to do the restart flow. In that flow a
sync dump is performed. Instead, schedule the dump worker before
requesting HW restart from mac80211. This approach simplifies the
restart flow.
Also, it is neeeded in order to differentiate between the handling of SW
and HW errors in a future commit.

From f826faaa1f3ab59458d43ced68dda30946844802 Mon Sep 17 00:00:00 2001

Subject: iwlwifi: pcie: switch to correct RBD/CD layout for 22560

The layout of the RBD (receive buffer descriptor) isn't quite right,
the hardware ended up being implemented differently. Switch to the
correct RBD layout. While at it, remove the now useless extra defines.

Also, switch the CD (completion descriptor) to the right format, which
is basically just a code cleanup because the only field we really used
(rbid) is still in the same place. We may need fragmentation later if
we ever want to use it.

Subject: iwlwifi: mvm: set max amsdu for TLC offload

mac80211 sets max amsdu to min supported ht vs vht but TLC only works
with one mode so we can set to the exact mode used (vht/ht)
and enable larger amsdu sizes for vht.

Subject: iwlwifi: dbg_ini: separate between ini and legacy dump flows

Separate between ini and legacy dump flows to allow adding ini triggers
that are not supported in the legacy flow and to increase readabilty.

iwl_fw_dbg_ini_collect function is now called with legacy trigger id and
_iwl_fw_dbg_ini_collect is called with ini trigger id.

Also make the actual dumping function static so that any dump collection
will go through iwl_fw_dbg_collect_sync.

Subject: iwlwifi: dbg_ini: add version to dump header

Add version to dump header to allow future changes of the dump struct,
once the ini debug flow becomes operational, without breaking backwards
compatibility.

Subject: iwlwifi: mvm: IBSS: use BE FIFO for multicast

Back in commit 4d339989acd7 ("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 cfbc6c4c5b91 ("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.

Subject: iwlwifi: dbg_ini: change memory range base address to u64

AX210 devices will use u64 for the base address to the DRAM monitor
buffer. To support this, change the structure for all device families
so both address sizes fit.

Also move range_data_size to the top of the struct to ease the parsing
of the memory range.

Subject: iwlwifi: dbg_ini: remove redundant type argument from
 iwl_dump_ini_mem

Since iwl_dump_ini_mem receive struct iwl_fw_ini_region_cfg which holds
the region type, there is no point to pass the type separately.

Subject: 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.

When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

Subject: iwlwifi: pcie: no need to check return value of debugfs_create
 functions

When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

Subject: 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.

Subject: 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).

Subject: iwlwifi: remove misconfigured pci ids from 22260 series

Two of the PCI ID entries for the 22260 series were incorrectly using
the subsystem vendor ID (which we ignore) as the PCI device ID.  This is
obviously wrong and can be simply removed since we already have the
correct entries in the list.
