d79749f771 ath10k: fix latency issue for QCA988x
(kvalo: cherry picked from commit 1340cc631b in
wireless-drivers-next to wireless-drivers as this a frequently reported
regression)

Bad latency is found on QCA988x, the issue was introduced by
commit 4504f0e5b5 ("ath10k: sdio: workaround firmware UART
pin configuration bug"). If uart_pin_workaround is false, this
change will set uart pin even if uart_print is false.

Tested HW: QCA9880
Tested FW: 10.2.4-1.0-00037

There were a bunch of devices with qu and jf that were loading the

accordingly.  Additionally, remove 0x1010 and 0x1210 subsytem IDs from

0f4f199443 iwlwifi: pcie: fix memory leaks in iwl_pcie_ctxt_info_gen3_init
In iwl_pcie_ctxt_info_gen3_init there are cases that the allocated dma
memory is leaked in case of error.

DMA memories prph_scratch, prph_info, and ctxt_info_gen3 are allocated
and initialized to be later assigned to trans_pcie. But in any error case
before such assignment the allocated memories should be released.

First of such error cases happens when iwl_pcie_init_fw_sec fails.
Current implementation correctly releases prph_scratch. But in two
sunsequent error cases where dma_alloc_coherent may fail, such
releases are missing.

This commit adds release for prph_scratch when allocation for
prph_info fails, and adds releases for prph_scratch and prph_info when
allocation for ctxt_info_gen3 fails.

08326a97af iwlwifi: pcie: fix indexing in command dump for new HW
We got a crash in iwl_trans_pcie_get_cmdlen(), while the TFD was
being accessed to sum up the lengths.

We want to access the TFD here, which is the information for the
hardware. We always only allocate 32 buffers for the cmd queue,
but on newer hardware (using TFH) we can also allocate only a
shorter hardware array, also only 32 TFDs. Prior to the TFH, we
had to allocate a bigger TFD array but would make those point to
a smaller set of buffers.

Additionally, now max_tfd_queue_size is up to 65536, so we can
access *way* out of bounds of a really only 32-entry array, so
it crashes.

Fix this by making the TFD index depend on which hardware we are
using right now.

While changing the calculation, also fix it to not use void ptr
arithmetic, but cast to u8 * before.

a2113cc44d iwlwifi: mvm: fix race in sync rx queue notification
Consider the following flow:
 1. Driver starts to sync the rx queues due to a delba.
    mvm->queue_sync_cookie=1.
    This rx-queues-sync is synchronous, so it doesn't increment the
    cookie until all rx queues handle the notification from FW.
 2. During this time, driver starts to sync rx queues due to nssn sync
    required.
    The cookie's value is still 1, but it doesn't matter since this
    rx-queue-sync is non-synchronous so in the notification handler the
    cookie is ignored.
    What _does_ matter is that this flow increments the cookie to 2
    immediately.
    Remember though that the FW won't start servicing this command until
    it's done with the previous one.
 3. FW is still handling the first command, so it sends a notification
    with internal_notif->sync=1, and internal_notif->cookie=0, which
    triggers a WARN_ONCE.

The solution for this race is to only use the mvm->queue_sync_cookie in
case of a synchronous sync-rx-queues. This way in step 2 the cookie's
value won't change so we avoid the WARN.

The commit in the "fixes" field is the first commit to introduce
non-synchronous sending of this command to FW.

The PHY is initialized during device initialization, but devices with
the tx_siso_diversity flag set need to send PHY_CONFIGURATION_CMD first,
otherwise the PHY would be reinitialized, causing a SYSASSERT.

initialization before a PHY_CONFIGURATION_CMD is received.

where we check if the package was read correctly, because we return
PTR_ERR(pkg) and if the table is not valid but the pointer is, we
would return a valid pointer as an error.  Fix that by moving the

895b5c9f20 netfilter: drop bridge nf reset from nf_reset
commit 174e23810c
("sk_buff: drop all skb extensions on free and skb scrubbing") made napi
recycle always drop skb extensions.  The additional skb_ext_del() that is
performed via nf_reset on napi skb recycle is not needed anymore.

Most nf_reset() calls in the stack are there so queued skb won't block
'rmmod nf_conntrack' indefinitely.

This removes the skb_ext_del from nf_reset, and renames it to a more
fitting nf_reset_ct().

In a few selected places, add a call to skb_ext_reset to make sure that
no active extensions remain.

I am submitting this for "net", because we're still early in the release
cycle.  The patch applies to net-next too, but I think the rename causes
needless divergence between those trees.

commands are transmitted through TX path.

But before HCI has been started, the TX path is not

are not enabled, hence TX interrupts will not be issued
after H2C skb has been DMAed to the device. And the H2C
skbs will not be released until the device is powered off.

Interrupt is disabled to stop PCI, which means the skbs

2d88b2cf2f iwlwifi: mvm: fix build w/o CONFIG_THERMAL
Without CONFIG_THERMAL, the driver fails to link as it calls
iwl_mvm_send_temp_report_ths_cmd() unconditionally. Fix this
by making that function available, but do almost nothing but
send the empty firmware command to enable CT-kill reporting.

While at it, also fix that function itself to not error out
when the thermal zone hasn't been initialized, but instead
just send the empty firmware command in this case as well.

479c4ee931 rtw88: add dynamic cck pd mechanism
This mechanism reduces the numbers of false alram in cck rate by
dynamically adjusting the value of power threshold and cs_ratio.
We determine the new value by three factors, which are rssi, false alarm
count and igi. Based on these factors, we define the current condition
into five levels. Compared to the previous level, if the level is changed,
we set the new values for power threshold and cs_ratio.

5227c2ee45 rtw88: 8822c: add SW DPK support
Power amplifiers are not linear components, and require DPK to
reduce its nonlinearity. DPK is called Digital Pre-distortion
Calibration, can be used to compensate the output of power.

DPK tracking is in charge of tracking the thermal changes. And
it then shifts the power curve accordingly, which makes the
power output remains linear even if the PA works in different
temperature.

To perform DPK, the parameter table should also be updated.
And the table will be applied when device is powered on.
Then DPK will reference the values to calibrate.

1ac3294bf7 rtw88: 8822c: add FW IQK support
Add support for doing IQK in firmware

Ideally the RF component's I/Q vectors should be orthogonal,
but usually they are not. So we need to calibrate for the RF
components, ex. PA/LNA, ADC/DAC.

And if the I/Q vectors are more orthogonal, the mixed signal
will have less deviation. This helps with those rates with
higher modulation (MCS8-9), because they have more strict
EVM/SNR requirement. Also the better of the quality of the
signal, the longer it can propagate, and the better throughput
performance we can get.
