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
d. Remove WAR to skip status ring entries if DMA is not done

Move RCC specific debug statistics to Data path
to avoid allocating nbuf for the PPDUs for which
MAC has not sent a Freeze TLV. Instead just update the
debug statistics at an earlier point irrespective of
MAC sending Freeze to PHY, to gather below information:
Status of number of PPDUs being captured by PHY
Status of MAC sending freeze TLV for the PPDUs
Update freeze reason for the number of PPDUs received
Add support to clear debug statistics at user's will.

Currently computation of Rx rate depends on Multi-user MCS
and NSS even for SU PPDU. For Single User PPDU, this becomes
invalid since computation of Rx rate should be based on SU MCS
and NSS.
To fix this, use respective PPDU information(MCS and NSS) and
calculate Rx rate based on ppdu_type.

STATUS_DONE is missing sometimes in monitor status ring,
but logging for each entry in the ring increases the time
for which the hal_ring access lock is held. If there are
many entries in the monitor status ring, this can lead to
the hal ring access lock being held for too long and cause
inconsistencies.
Reduce the logging level of the tlv tag STATUS_DONE errors
and have a counter for the cases when this happens.

Size of rx_pkt_hdr tlv structure is used to check if there is enough
space in the SKB to add radiotap header.
The issue is seen due to a single SKB can hold the multiple TLVs and
the next subsequent SKB has the data. In this case, there is no headroom
available in the second SKB. Therefore crash seen while adding the
radiotap header in the second SKB.
To fix this issue, check if the SKB has enough headroom space. If not,
