In non concurrency scenario with TDLS Offchan link, FW is sending
two pauses namely PAUSE_TYPE_CHOP and PAUSE_TYPE_CHOP_TDLS_OFFCHAN
back to back when DUT dwells between TDLS Off channel and AP channel
respectively. HOST handles these events as vdev based event instead
of peer based event and remove all the tx queues from scheduler for
all the peer irrespective of the pause type. This will lead to data
stall in TDLS offchan scenarios, as at any point of time, host will
be receiving one of the two pauses and keep its peer queues out of
scheduler.
Changes are done to decouple the handling of pause/unpause events
for TDLS peers with Offchan enabled from vdev based pause/unpause.
TDLS peers will be paused/unpaused based on PAUSE_TYPE_CHOP_TDLS_OFFCHAN
pause type. Other pause/unpause events will be handled as usual.

Presently in the driver, we get the MSI interrupt to wake up from
suspend which directs the call to the both kernel and driver. In the
driver, the HIF callback target_initial_wakeup_cb registered, gets
called in interrupt context while that through the kernel get scheduled
in thread context. These two call can potentially get into a deadlock.
The scenario can be described as:
- MSI interrupt raised
- callback invoked from kernel -> takes spinlock on psoc->lock
- hif callback in interrupt context -> spins on the same psoc->lock
- deadlock
The problem arises due to the fact that both the kernel thread and the
interrupt handler are executing on the same CPU. This causes the
spinlock in the interrupt context to spin forever.
The solution to mitigate this scenario is to not take the reference
inside the hif callback pmo_core_psoc_handle_initial_wake_up. This
reference was put in place to prevent the wake up callback from getting
affected by psoc creation and deletion. But there seems no need for this
as creation and deletion of psoc happens outside the time-scope of the
wake up callback.

While processing QCA_WLAN_VENDOR_BEACON_REPORTING_OP_START vendor
cmd, the expectation is FW should not wakeup host if host is in
wow mode. Wakeup of HOST happens purely based on Nth beacon
WMI event WMI_VDEV_PARAM_NTH_BEACON_TO_HOST config to firmware
where host gives Nth value and MSB bit to indicate whether
to wake up host or not. MSB bit is 1 means fw should not wakeup
host(By default MSB bit is 0).
WOW_BEACON_EVENT registration on host is required only in case
if HOST sends WMI_RMV_BCN_FILTER_CMDID in order to allow fw to send
connected AP beacons. Currently, HOST sends NTH BEACON CMD to fw with
MSB bit of Nth value equal to 1 in order to allow send connected AP
beacons to HOST only if HOST is not in wow mode.
Fix is to remove default WOW_BEACON_EVENT registration for STA on host.
