In case the bus is in low power mode, the register writes (followed by a
memory barrier) may take a long time (~4ms). This can cause the caller
to block till the PCIe write is completed. Thus, even though PCI
writes are posted, it can still block the caller.
Hence, in case the bus is in low power mode (not in M0), or not in high
throughput scenarios, queue the register write in a workqueue. The
register write will happen in the delayed work context. In other cases,
i.e ,when the bus is not in low power mode or in high thoughput
scenarios, do the register writes in caller context.

This change fixes issue with EAPOL frames in Tx capture
EAPOL frames completions are received with ACK completion.
For ACK completion, ba_size, ba_bitmap, ba_seqno are not updated earlier.
it was leading to dropping the frames in driver.
This fix updates ba_size, ba_bitmap, ba_seqno for QOS TID frames in ACK

If RX packets reaped from REO2SW ring hit rx_reap_loop_pkt_limit,
REO2SW ring reaping will break and stop, but for scattered msdu case,
all related buffer should be received one time for further processing,
otherwise dp_rx_sg_create can not handle correctly.
(1) make sure all buffers for scattered msdu is received then allow
break when rx_reap_loop_pkt_limit hit.
(2) refine skb unmap location in case msdu_scatter_wait_break logic is
hit, then may double unmap for same skb(not for current issue).

In current monitor status ring implementation,
on pdev_attach, (srng->num_entires – 1) entries
(to keep one entry slot between hp and tp)
are replenished and last entry is not replenished to HW.
With qcn9000 monitor mode HW enhancements, status and destination ring
can be made lock-stepped.
for qcn9000 lock step is achieved by making monitor status ring
follow the monitor destination reap for a PPDU
However in existing flow during attach monitor status replenish logic
do not fill last entry but is filled up during first subsequent reap.
for first ppdu, i.e. after reaping destination ring,
when status ring is reaped, as first entry (hp = srng->num_entires – 1)
in status ring is NULL, so lock-stepping is not achieved.
To address this issue for qcn9000 as well as HK:
a. Replenish last entry in monitor status ring during attach
b. Modify src srng peek API to peek it from hp+1 entry
c. Introduce new HAL API get cur desc and move next

Macro ATH_11AC_TXCOMPACT is defined, so CE4 sending completion will
not free the related htt_htc packets. Currently it depends on
htt_soc->htt_htc_pkt_misclist to free them once this kind of htt_htc
is no longer sitting in CE4 source ring which means CE sending
completion is done already. misclist will free the old/tail of
htt_htc packets if there is > 256 htt_htc packet is pending in list,
but CE4 source ring has 2048 entries, for extreme case, if CE4 sending
is blocking and > 256 htt_htc packets is pending in CE4,
misclist will free the tail htt_htc packet, but later CE4 sending
completion is coming, invalid access to htt_htc packets will happen.
Enlarge misclist trim threshold > 2048 to ensure that when free
htt_htc packet in misclist, the htt_htc packets has done sending
completion already.
