certain fields are now retrieved from reo_destination
ring to nbuf cb. This avoids accessing the RX_TLVs
which are spread across two cache lines. This is
helping improve small pkt (64 byte) performance.

Currently, if BA session for a tid is active, we tear down

to send new addba req. But this is not happening, therefore
we accept new addba req after flushing tid queue and then setup

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.

are not routed correctly to IPA ring. Currently only

is enabled. Upon IPA offload is disabled, save values

Reduce pdev pool size could significantly reduce firmware wmm drop. Both

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.

Currently vdev deletion happens as a part of last
peer's unma and vdev creation happens in a different context invoked
by the upper layer in dp_vdev_attach_wifi3.
In a scenario when the old vdev is being deleted and a new one is being
created, with the same vdev id (e.g. P2p -> SAP transition), its
possible that the old and new vdevs co-exist in the pdev->vdev_list
at the same time. In such a case, the API (get_vdev_from_vdev_id) can
return the old stale vdev, even when a new vdev has been created. This
is not the expected behaviour.
Check for "delete.pending" flag before returning the vdev. If the flag
is set, skip that vdev.

On low memory system, skb allocation failures are observed in
dp_rx_buffers_replenish during driver loading phase within
dp_rx_pdev_attach code path. Per kernel memory team analysis,
failures are caused by large amount of atomic allocations.
Currently when replenishing RX buffers, srng spinlock is first
grabbed and then skb buffers are being requested, which makes
skb allocation happen in atomic context.
Fix is to create a new API for refilling rx buffers when
loading driver. In the API, skbs are allocated into a
pool without srng lock grabbed. Srng lock is grabbed only
when refilling already allocated skb to rxdma ring.
