RBUFCAP support added in FW.
The RBUFCAP feature is amendment to the block ack mechanism to
prevent overloading of the recipient’s memory space, which may
happen in case the link speed is higher than STA’s capability
to process or consume incoming data.
The block ack policy (ba_policy) is now controlled by FW so driver
should ignore this field.
Add new debugfs "rbufcap" to configure RBUFCAP.

The driver updates Tx status ring HW tail only after it finishes
processing the whole status ring, while the HW is still transmitting
from other transmit rings. This can cause back-pressure on HW if
no status entries are available.
Update HW tail of Tx status ring without waiting for the end of the
processing to help feeding back the HW with status entries and to allow
additional packet transmission.

With multiple clients and in high throughput scenarios, Tx status ring
can get full and become a bottleneck in Tx transmission.
Set the default Tx status ring size order to 13, previous value was 12.
This will double the status ring size from 4K entries to 8K entries.

Currently the FW is reset on every interface type change, because
of various FW bugs.
FW reset is not required when switching from STA to P2P client, hence
can be skipped.

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.

This patch removes the error branch for (queue > ar->hw->queues).
It is no longer needed anymore as the "queue" value is validated by
cfg80211's parse_txq_params() before the driver code gets called.
Some background:
In the old days (linux 2.6 and early 3.x), the parse_txq_params()
function did not verify the "queue" value. That's why these drivers
had to do it.

This patch follows Alan Stern's recent patch:
"p54: Fix race between disconnect and firmware loading"
that overhauled carl9170 buggy firmware loading and driver
unbinding procedures.
Since the carl9170 code was adapted from p54 it uses the
same functions and is likely to have the same problem, but
it's just that the syzbot hasn't reproduce them (yet).
a summary from the changes (copied from the p54 patch):
* Call usb_driver_release_interface() rather than
device_release_driver().
* Lock udev (the interface's parent) before unbinding the
driver instead of locking udev->parent.
* During the firmware loading process, take a reference
to the USB interface instead of the USB device.
* Don't take an unnecessary reference to the device during
probe (and then don't drop it during disconnect).
and
* Make sure to prevent use-after-free bugs by explicitly
setting the driver context to NULL after signaling the
completion.

In commit 3c0efb745a17 ("ath9k: discard undersized packets")
the lower bound of RX packets was set to 10 (min ACK size) to
filter those that would otherwise be treated as invalid at
mac80211.
Alas, short radar pulses are reported as PHY_ERROR frames
with length set to 3. Therefore their detection stopped
working after that commit.
NOTE: ath9k drivers built thereafter will not pass DFS
certification.
This extends the criteria for short packets to explicitly
handle PHY_ERROR frames.

Integrated WiFi chipset ex:WCN399x supports fw logging
using WMI copy engine and shared mem DIAG based fw logging.
By default shared mem DIAG based fw logging is enabled.
To support WMI copy engine based fw logging add QMI
control message to enable WMI copy engine based fw logging.
Enable WMI based fw logging using fw_diag_log module parameter.
insmod ath10k_core.ko fw_diag_log=1
DIAG utility(https://github.com/andersson/diag) implements extraction
of diagnostics related messages between application processor and
various subsystems while shared mem DIAG based fw logging is enabled.

This patch will add the support to control the transmit power for traffic
to a station associated with the AP.
Underlying firmware will enforce that the maximum tx power will be based
on the regulatory requirements. If the user given transmit power is greater
than the allowed tx power in the given channel, then the firmware will use
the maximum tx power in the same channel.
Max and Min tx power values will depends on no of tx chain masks,
for QCA9984 allowed tx power range values from 6 to 23.
When 0 is sent to the firmware as tx power, it will revert to the default
tx power for the station.

Peer creation in firmware fails if last peer deletion is still
in progress.
The firmware sends a peer delete response event if it advertises
the service WMI_SERVICE_SYNC_DELETE_CMDS. This peer delete response
event is used to synchronize the peer deletion.
Add peer delete response event and wait for the event after
deleting every peer from host driver to synchronize with firmware.

Observed PCIE device wake up failed after ~120 iterations of
soft-reboot test. The error message is
"ath10k_pci 0000:01:00.0: failed to wake up device : -110"
The call trace as below:
ath10k_pci_probe -> ath10k_pci_force_wake -> ath10k_pci_wake_wait ->
ath10k_pci_is_awake
Once trigger the device to wake up, we will continuously check the RTC
state until it returns RTC_STATE_V_ON or timeout.
But for QCA99x0 chips, we use wrong value for RTC_STATE_V_ON.
Occasionally, we get 0x7 on the fist read, we thought as a failure
case, but actually is the right value, also verified with the spec.
So fix the issue by changing RTC_STATE_V_ON from 0x5 to 0x7, passed
~2000 iterations.

Currently, below fixed rate commands are broken,
iw wlanx set bitrates legacy-<2.4|5> ht-mcs-<2.4|5> vht-mcs-<2.4|5> \
<NSS:MCSx>
iw wlanx set bitrates legacy-<2.4|5> <legacy rate> ht-mcs-<2.4|5> \
vht-mcs-<2.4|5> <NSS:MCSx>
There are two methods to set fixed rate, both failed,
- Use vdev fixed rate command
This command only support one single rate, but it's broken due to
mac80211 change commit e8e4f5280ddd ("mac80211: reject/clear user
rate mask if not usable"), which requires user to specify at least
one legacy rate. So we can't use this command to set ht/vht single
rate any more.
- Use peer_assoc command
This command can update rx capability for multiple rates, it will
work fine for ht mcs rates, as each supported mcs can be advertised
in ht_mcs index mask. But this will not work with vht rates because,
as per the vht mcs capability advertisement, there are only two bits
to indicate the supported mcs. E.g. only support 0-7, 0-8, 0-9.
So introduced new WMI command: WMI_PEER_PARAM_FIXED_RATE. After peer
assoc, the peer fixed rate cmd will work for that specific peer.
Remaining peers will use auto rate. If both vdev fixed rate and peer
fixed rates are given, peer fixed rate will take effect to peers for
which this cmd is given. Remaining peers in that vdev, will use vdev
fixed rate.

On SMP platform, when continuously running wifi up/down, the napi
poll can be scheduled during chip reset, which will call
ath10k_pci_has_fw_crashed() to check the fw status. But in the reset
period, the value from FW_INDICATOR_ADDRESS register will return
0xdeadbeef, which also be treated as fw crash. Fix the issue by
moving chip reset after napi disabled.

For QCA988X target, pktlog gives details of the tx bitrate
which is used in the driver for station info.
Enabling pktlog by default will cause more interrupts
in target to host CE pipe, which can impact more CPU usage
for targets ex:WCN3990 and also not required for all other
platforms (eg: WCN3990), for getting tx bitrate.
Enable pktlog only for QCA988X based on hardware params.

ath10k_dbg() is called in ath10k_process_rx() with huge set of arguments
which is causing CPU overhead even when debug_mask is not set.
Good improvement was observed in the receive side performance when call
to ath10k_dbg() is avoided in the RX path.
Since currently all debug messages are sent via tracing infrastructure,
we cannot entirely avoid calling ath10k_dbg. Therefore, call to
ath10k_dbg() is made conditional based on tracing config in the driver.
Trasmit performance remains unchanged with this patch; below are some
experimental results with this patch and tracing disabled.

This is done in order to make the *htt_h2t_aggr_cfg_msg* op align better
with the rest of the htt ops (whom all have inline wrappers).
It also adds support for the case when the op is missing (function
pointer is NULL).
As a result of this, the name of the 32 bit implementation in htt_tx.c
was changed and the function was made static.

====================
wireless-drivers-next patches for 5.3
First set of patches for 5.3, but not that many patches this time.
This pull request fails to compile with the tip tree due to
ktime_get_boot_ns() API changes there. It should be easy for Linus to
fix it in p54 driver once he pulls this, an example resolution here:
https://lkml.kernel.org/r/20190625160432.533aa140@canb.auug.org.au
Major changes:
airo
* switch to use skcipher interface
p54
* support boottime in scan results
rtw88
* add fast xmit support
* add random mac address on scan support
rt2x00
* add software watchdog to detect hangs, it's disabled by default

For some SDIO chip, the peer id is 65535 for MPDU with error status,
then test_bit will trigger buffer overflow for peer's memory, if kasan
enabled, it will report error.
Reason is when station is in disconnecting status, firmware do not delete
the peer info since it not disconnected completely, meanwhile some AP will
still send data packet to station, then hardware will receive the packet
and send to firmware, firmware's logic will report peer id of 65535 for
MPDU with error status.
Add check for overflow the size of peer's peer_ids will avoid the buffer
overflow access.

driver tries to configure probe response template for mesh, but
it fails because the interface type is not NL80211_IFTYPE_AP but

For SDIO chip, it does not have HTT connect step in boot phase of UTF
mode, so it does not need the swap configuration for UTF mode, otherwise
it will trigger UTF load fail. For normal mode, it is swap between HTT

HTT and WMI.
Disable swap mail box for UTF mode will let UTF mode load success.

When MISC interrupt is triggered due to HALP bit, in parallel
to mbox events handling by the MISC threaded IRQ, new mbox
interrupt can be missed in the following scenario:
1. MISC ICR is read in the IRQ handler
2. Threaded IRQ is completed and all MISC interrupts are unmasked
3. mbox interrupt is set by FW
4. HALP is masked
The mbox interrupt in step 3 can be missed due to constant high level
of ICM.
Masking all MISC IRQs instead of masking only HALP bit in step 4
will guarantee that ICM will drop to 0 and interrupt will be triggered
once MISC interrupts will be unmasked.
