STATUS_BUFFER_DONE tlv written in first word for a status
buffer indicates that DMA is done for that status ring entry.
In existing implementation, for a status ring entry if
STATUS_BUFFER_DONE tlv is not written by HW, we poll on to status ring
entry until DMA is done by HW.
During lmac reset it may happnen that HW will not write STATUS_BUFFER_DONE
tlv in status buffer, in that case we end up polling infinitely leading
to backpressure on monitor status ring.
As per MAC team's suggestion, when HP + 1 entry is peeked and if DMA
is not done and if HP + 2 entry's DMA done is set,
replenish HP + 1 entry and start processing in next interrupt.
If HP + 2 entry's DMA done is not set,
poll onto HP + 1 entry DMA done to be set.

Skip protocol tag updating from msdu end TLV protocol tag meta data
when there is RXDMA REO entrance push error on monitor destination ring.
The attention and msdu end TLV is not updated reliably when there
is RXDMA REO entrance push error such as FCS error on monitor
destination ring.

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.

Drop MPDUs received with rxdma_overflow_err, rxdma_flush
or rxdma_mpdu_length_err errors on monitor RXDMA2SW ring
since Rx TLVs are not populated properly by HW.

This change is for supporting monitor mode VAP. All the monitor mode ring
is configured. The related monitor mode ring includes:
-monitor mode buffer ring
-monitor mode destination ring
-monitor mode status ring
-monitor mode link descriptor ring
The packet is not sent to monitor mode ring unless the monitor mode VAP is
configured. This release support Multiple VAP - AP/STA VAP plus Monitor
VAP configuration. The status ring is not used in this release. However,
the ring is tested and the ring is moving and there are TLV's in the ring.
