Use chip ID and destination peer to determine the target soc
and partner vdev for Intra-BSS in MLO case.

in some corner cases (ex: SG frames are received) we
do not decrement quota or num_pending and go and fetch
the next descriptor, chances are ring may not have valid
descriptors at that point of time hence added this sanity
check.

Following peer stats are updated in per packet Rx path:
to_stack
multicast
broadcast
In BE architecture, HW provides the support for basic vdev stats and
hence per packet stats updation of above parameters can be done only
when enhanced stats is enabled or HW vdev offload stats is disabled.
Avoiding per packet stats updation reduces CPU load and improves KPI.

Prefetch RX HW desc, SW desc and SKB in pipeline
fasion in the first loop of RX processing.
This has improved TPUT by 200Mbps and provided a
10% gain in CPU (single core)
PINE with other optimizations: 3960Mbps @ 100% core-3
PINE + pipeline prefetch: 4130Mbps @ 90% core-3

Added an API to do a batch invalidation of REO descs
saw an improvement of 40 to 45 Mbps.
Note: this change is applicable only for cached
descriptors
PINE with Default driver: 3189 @ 100% core-3
PINE with skb prefetch: 3469 @ 100% core-3
PINE with skb pre + batch inv: 3506 @ 100% core-3

Tid in RX frame header may be larger than MAX TID allowed
value, this will lead a out of boundary array access and
lead to kernel crash at last. Change is aimed to do a TID
check and discard such frame when necessary.

For DA MC/BC RX frame, host should not use da_idx to access soc->ast_table

sw_exception bit will be marked in reo dest ring descriptor for
FW re-injected frame, get this bit and save it in skb->cb,
this bit value can be used for FISA further check.
there is no reo_dest_indication field in reo dest ring on beryllium,
so share same cb member for sw_exception and reo_dest_indication.

In Beryllium the HW does the ast lookup and match
and sets the intra-bss bit in the msdu_desc_info
structure of reo_destination ring and WBM Rx release ring.
So, change the Beryllium code to make use of this
hardware assistance for intra-bss.

The bridge forwards the multicast packets to all the
interfaces attached the bridge.
When the STA network interface receives such packets
from bridge and send it to the AP, it is echoed back
from the BSS.
These packets are not intended for the bridge as it
will lead to looping.
Add a check to detect and drop such packets when
received back from the BSS.

The existing assertions for unmapped variable in
rx descriptor results in an undesired bug_on since
the unmapped value is 0 for active descriptors.
The fix is to modify this assertion so that bug_on will
be triggered only if the unmapped value is 1 in rx
desc.
