Avoid using ast_entry in intra_bss handling, instead use
da_peer_id directly from the msdu_metadata
Change-Id: Ic586f297e8e393504d7d399cff7a67c3035aa11f
This change includes below
1) Changes needed to increase Tx rings to 4
2) Use WBM2SW4 ring for rx error in QCN9224
3) memset srng at alloc to avoid populating RBM_id
in per packet path and enable implicit RBM

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.

WDI event WDI_EVENT_UPDATE_DP_STATS is triggered for updation of peer
stats from both per packet and monitor path wherein per packet path is
applicable for MCC and monitor path is applicable for WIN.
Trigger for this event is flag protected under the macros
FEATURE_PERPKT_INFO and WDI_EVENT_ENABLE.
FEATURE_PERPKT_INFO is not defined for MCC.
With this, WDI event in per packet path is not triggered and hence unused.
Make changes to remove the unused code.

Currently, rx packet capture events processing happens even
when feature is disabled by ini. This incurs per packet overhead
in rx path.
The fix is to move all the processing from rx path to packet capture mode
component. Send only wdi event from rx path, when feature is enabled by
ini.

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.

skb_set_len and skb_pull operations are done in both
dp_rx_deliver_to_pkt_capture_no_peer and
dp_rx_deliver_to_stack_no_peer. Due to this, in the
issue scenario, EAPOL frame gets dropped in roaming
scenario since qdf_nbuf_is_ipv4_eapol_pkt returns
false.
Fix is to do a skb_push_head operation in
dp_rx_deliver_to_pkt_capture_no_peer API before

In monitor mode, when the channel is set to any 2G band channel
the mac_id passed to dp_mon_process API is 1. As part of
dp_rx_buffers_replenish, refill history is logged and the
mac_id is used to index into the history array. The array is
of size 1 and OOB access would happen when ring_num which
is the mac_id, passed in is 1.
Fix is to pass the pdev->lmac_id instead to
dp_rx_refill_ring_record_entry and add ring_num sanity check.

When a msdu scattered across multiple nbufs is received
in REO2SW ring and the remaining nbufs are not yet
available in the ring, loop in dp_rx_process is exited
without resetting the invalid bit in the ring desc cookie.
This will result in an incorrect assertion failure when
the same entry is processed the next time.
Fix is to reset the invalid bit in ring desc cookie
when the loop is exited in the above msdu scattered
scenario.

MSDU with len 1654 is received in the REO2SW ring and

checks for strictly less than 2048 bytes which results
in the assertion failure.
Fix is to add the equal case when validating the
