The current implementation is reading the wrong eeprom type.
Fixes: d8ec2e2a63e8 ("ath9k: Add an eeprom_ops callback for retrieving the eepmisc value")

Replace other constants with AR9300_MAX_CHAINS when appropriate.

This makes the code clearer since set11nRateFlags currently sets
both the rate flags and chain sel. This may also be required for
QCN550x support, where the rate flags and chain sel are in separate
fields.

This makes the macros more consistent and removes hidden dependencies on
ah for macros that take _ah as a parameter.

When more clients (128) are connected, the UL data traffic
KPI measurement is low compared to single client. This issue
is due to more CPU cycles spent on the peer lookup operation
with more clients. So reduce the peer lookup operation by
modifying the linear based lookup operation into the rhash
based lookup operation. This improve the peak throughput
measurement. Since this is a software algorithm change, it is
applicable for all the platforms.
TCP UL 128 Clients test case Observation (64bit system):
Previous: ~550 Mbps
Now : ~860 Mbps

This is to read variant from SMBIOS such as read from DT, the variant
string will be used to one part of string which used to search board
data from board-2.bin.

Sometimes it has a variant value which read from DT or SMBIOS by
ath11k, and meanwhile it does not have the matched board name in
board-2.bin, then it will failed at boot up phase.
Add fallback board name which removed variant value and search again
in board-2.bin when failed with variant and try to load the board
data again to increase boot up success rate.

In Qualcomm ARM platforms there is WL_EN pin and other power regulators
which can be controlled at platform side to completely reset the chip.
For most of x86 and other platforms, the chip is connected via PCIe M.2
interface, and there is no way to control WL_EN pin. Instead the host
driver needs to reset the chip via PCIE_SOC_GLOBAL_RESET hardware
register, just like ath11k does currently.
But when using PCIE_SOC_GLOBAL_RESET there are some hardware registers
which are not cleared/restored. To handle those cases we can enable
PLATFORM_CAP_PCIE_GLOBAL_RESET QMI host capability to tell the firmware
to do some platform specific operations after firmware download.
This does not fix any known issues, but is recommended by the firmware
team, so enable the capability on QCA6390 and WCN6855 PCI devices. It is
currently unclear if this should be enabled also on QCN9074, so leave it
disabled for now. On AHB devices this is not needed as they don't use
PCIE_SOC_GLOBAL_RESET.

Reason is mhi_deassert_dev_wake() from mhi_device_put() is called
but mhi_assert_dev_wake() from __mhi_device_get_sync() is not called
in progress of recovery. Commit 8e0559921f9a ("bus: mhi: core:
Skip device wake in error or shutdown state") add check for the
pm_state of mhi in __mhi_device_get_sync(), and the pm_state is not
the normal state untill recovery is completed, so it leads the
dev_wake is not 0 and above warning print in mhi_pm_disable_transition()
while checking mhi_cntrl->dev_wake.
Add check in ath11k_pci_write32()/ath11k_pci_read32() to skip call
mhi_device_put() if mhi_device_get_sync() does not really do wake,
then the warning gone.

Add hw-restart to directly restart wlan. Like UTF mode start it will
restart hardware and download firmware again.
Usage:
1. Run command:
echo hw-restart > /sys/kernel/debug/ath11k/qca6390\ hw2.0/simulate_fw_crash
echo hw-restart > /sys/kernel/debug/ath11k/wcn6855\ hw2.0/simulate_fw_crash
2. wlan will be restart and do recovery process and success.

ieee80211_reconfig() of mac80211 is the main function for recovery of
each ieee80211_hw and ath11k, and ath11k_core_reconfigure_on_crash()
is the main function for recovery of ath11k_base, it has more than
one ieee80211_hw and ath11k for each ath11k_base, so it need to add
synchronization between them, otherwise it has many issue.
For example, when ath11k_core_reconfigure_on_crash() is not complete,
mac80211 send a hw scan request to ath11k, it leads firmware crash,
because firmware has not been initialized at that moment, firmware
is only finished downloaded and loaded, it can not receive scan
command.

Currently ath11k has device recovery logic, it is introduced by this
patch "ath11k: Add support for subsystem recovery" which is upstream
by https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/commit/?h=ath11k-bringup&id=3a7b4838b6f6f234239f263ef3dc02e612a083ad.
The patch is for AHB devices such as IPQ8074, it has remote proc module
which is used to download the firmware and boots the processor which
firmware is running on. If firmware crashed, remote proc module will
detect it and download and boot firmware again. Below command will
trigger a firmware crash, and then user can test feature of device
recovery.
Test command:
echo assert > /sys/kernel/debug/ath11k/qca6390\ hw2.0/simulate_fw_crash
echo assert > /sys/kernel/debug/ath11k/wcn6855\ hw2.0/simulate_fw_crash
Unfortunately, QCA6390 is PCIe bus, it does not have the remote proc
module, it use mhi module to communicate between firmware and ath11k.
So ath11k does not support device recovery for QCA6390 currently.
This patch is to add the extra logic which is different for QCA6390.
When firmware crashed, MHI_CB_EE_RDDM event will be indicate by
firmware and then ath11k_mhi_op_status_cb which is the callback of
mhi_controller will receive the MHI_CB_EE_RDDM event, then ath11k
will start to do recovery process, ath11k_core_reset() calls
ath11k_hif_power_down()/ath11k_hif_power_up(), then the mhi/ath11k
will start to download and boot firmware. There are some logic to
avoid deadloop recovery and two simultaneous recovery operations.
And because it has muti-radios for the soc, so it add some logic
in ath11k_mac_op_reconfig_complete() to make sure all radios has
reconfig complete and then complete the device recovery.
Also it add workqueue_aux, because ab->workqueue is used when receive
ATH11K_QMI_EVENT_FW_READY in recovery process(queue_work(ab->workqueue,
&ab->restart_work)), and ath11k_core_reset will wait for max
ATH11K_RESET_TIMEOUT_HZ for the previous restart_work finished, if
ath11k_core_reset also queued in ab->workqueue, then it will delay
restart_work of previous recovery and lead previous recovery fail.
ath11k recovery success for QCA6390/WCN6855 after apply this patch.

ath11k_peer_find_by_addr states via lockdep that ab->base_lock must be
held when calling that function in order to protect the list. All
callers except ath11k_mac_op_unassign_vif_chanctx have that lock
acquired when calling ath11k_peer_find_by_addr. That lock is also not
transitively held by a path towards ath11k_mac_op_unassign_vif_chanctx.
The solution is to acquire the lock when calling
ath11k_peer_find_by_addr inside ath11k_mac_op_unassign_vif_chanctx.
I am currently working on a static analyser to detect missing locks and
this was a reported case. I manually verified the report by looking at
the code, but I do not have real hardware so this is compile tested
only.

Currently after the hardware restart triggered from the driver,
the station interface connection remains intact, since a disconnect
trigger is not sent to userspace. This can lead to a problem in
targets where the wifi mac sequence is added by the firmware.
After the target restart, its wifi mac sequence number gets
reset to zero. Hence AP to which our device is connected will receive
frames with a wifi mac sequence number jump to the past, thereby
resulting in the AP dropping all these frames, until the frame
arrives with a wifi mac sequence number which AP was expecting.
To avoid such frame drops, its better to trigger a station disconnect
upon target hardware restart which can be done with API
ieee80211_reconfig_disconnect exposed to mac80211.
The other targets are not affected by this change, since the hardware
params flag is not set.

It is not recommened to use platform_get_resource(pdev, IORESOURCE_IRQ)
for requesting IRQ's resources any more, as they can be not ready yet in
case of DT-booting.
platform_get_irq() instead is a recommended way for getting IRQ even if
it was not retrieved earlier.
It also makes code simpler because we're getting "int" value right away
and no conversion from resource to int is required.

IEEE80211_CONF_CHANGE_MONITOR would be set every time even when vif runs as
sta mode.
If vif runs as sta mode, the beacon filter would be falsely enabled
earlier than the associated state.
That is not the behavior the firmware expects and also breaks the original
logic of sta mode. Thus, we only limit the operation to set the beacon
filter only for monitor mode when IEEE80211_CONF_CHANGE_MONITOR is set.
