In monitor destination ring, sometime buffer with
msdu_len zero is observed.
Drop frame if msdu len is zero.

In monitor mode, if channel is initially configured from 5G
band and then moved to channel from 2G band, packets are still
received on MAC-0 RXDMA2SW ring since IMPS is disabled for both
MACs. Since driver reaps only MAC-1 RXDMA2SW ring, ring full
condition is hit for the MAC-0 ring causing ring backpressure.
Fix is to drop packets received on the non-monitoring MAC
ring.

In Monitor mode, frag len is not adjusted taking l2 hdr
padding into consideration. This will result in inclusion
of l2 hdr padding length twice in skb len and would cause
skb expansion due to length exceeding 2048 bytes.
Fix is to adjust frag len taking l2 hdr padding into
consideration.

Macro MAX_MONITOR_HEADER is used to specify the max. headroom size for
different buffer rings. With the monitor frag feature, macro
DP_RX_MON_MAX_MONITOR_HEADER is required to specify the headroom size for
the monitor destination buffers as per the the approch being used.

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.

With the init/de-init FR we set the minimum buffers
needed in monitor buffer ring to be 8, because the low

to monitor status ring, this resulted in NAC feature

In dp_rxdma_get_mon_buf_ring returns mac id index of
rx_refill_buf_ring array. But for targets with only one

to replenish failures in case of monitor mode when mon dest

A framework is added where the filters for every
mode are stored on a radio instance. Whenever a mode comes
up, it stores the filters in the radio and calls a
common API which iterates through all the enabled
mode filters and loops through them to create a
superset of filters which is sent to HTT.
This framework can be extended for new feature addition
which set filters for the monitor status and monitor
destination rings.

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.
