done the following changes to improve the RX path KPI
1. remove the extra invalidate in RX path as
we no longer dirty the RX TLV cache lines.
we now store the rx error codes in nbuf cb instead
of RX TLVs reserved memory bytes.
2. with features like flow tag and wds extended mode
enabled by default, the rx_fast_flag is always set
to false, this resulted in lot more instructions
being executed in RX path.
Now we ensured this flag is at least set for other
features which are not enabled by default.

Remove wapi frames from is_eapol check in dp_rx_null_q_desc.
This change is to address the below issue:
First wapi packet received in dp_rx_nll_q_desc,
before TID setup does not reach stack since it is
treated as an eapol frame and gets dropped in
dp_rx_eapol_deliver_to_stack.

In case of where multiple scatter gather frames are
part of same MPDU last_mpdu_in_msdu will be set only
for last buffer of last scatter frame in MPDU.
Below is the hw descriptors bits when 2 scatter frames
are part of a MPDU
-----------------------------------------------------------
|Buffer_num | MSDU_NUM | first_in_mpdu | cont | last_in_mpdu |
-----------------------------------------------------------
| 1 | 1 | 1 | 1 | 0 |
-----------------------------------------------------------
| 2 | 1 | 0 | 0 | 0 |
-----------------------------------------------------------
| 3 | 2 | 0 | 1 | 0 |
-----------------------------------------------------------
| 4 | 2 | 0 | 0 | 1 |
-----------------------------------------------------------
In above case scatter MSDU boundary checks can be done only
based on continuation bit. So while reaping use continuation
bit instead of last_in_mpdu bit to detect boundary

In BE architecture, HW provides the support for basic vdev stats and

Avoiding per packet stats updation reduces CPU load and improves KPI.

When the STA network interface receives such packets
from bridge and send it to the AP, it is echoed back

These packets are not intended for the bridge as it
