If any non authed clients send data packets then
AP should send Deauth Frames to STA. In Current code
we are finding VAP from pdev. And if MAC address are
same for VAPs on both radios then pdev will be wrong.
Because of that VDEV id was coming for non active VAP
and deauth frames were not going out of AP.

basically tried reading peer_id from peer structure
to avoid 1 cache-line miss per pkt and access mac address
from frame data for WDS only if WDS condition is valid.
The other optimization is to avoid accessing queue_mapping
field of skb for skb received which is at 140 offset
This again helps to avoid i cache miss.
Another place is to do a memcpy only when we intend to

CCE stats are reported across rings today. Since HKv2 is a SMP, it
creates the possibility of missing stats when two or more CPUs are
updating the counters for the same protocol type. In order to avoid
this, we can either use locks or store stats on a per-CPU basis.
Since tagging happens on the core data path, locks are not preferred.
Instead, we use a per-ring counter, since each CPU operates on a REO
ring. Exception packets today go to Ring-0 (also normal rx Reo-0
go to Ring-0). Hence tags are maintained separately for exception
ring as well.

With this feature, using appropriate commands, link layer, network layer,
transport layer and some of the application protocols can be tagged with
the user provided tag values for easier identification of protocols. The
supported protocols today are as follows.
ARP, DHCPv4, DHCPv6, DNS over TCP (v4), DNS over TCP (v6), DNS over UDP
(v4), DNS over UDP (v6), ICMPv4, ICMPv6, TCPv4, TCPv6, UDPv4,
UDPv6, IPv4, IPv6, EAP.
Receive packets are tagged by hardware. Tags are applied after the first
matching rule. Hence it is recommended that the rules are
programmed in such a way that tags are configured from application layer
to data link layer to get expected results.
