Currently cached rx buffer frames are forwarded to stack
at the time of successful association completion. If the
association with the AP is unsuccessful frames are not
flushed and this leads to memory leak. To fix this clear

Deadlock happens when control path takes scn_lock and calls
dp_peer_unref_delete() which in tern tries to acquire peer_ref_mutex.
At the same time, if other core starts handling peer_unmap by acquiring
peer_ref_mutex and calls dp_reset_and_release_peer_mem() which in turn
calls ol_ath_node_free() and tries to acquire scn_lock leading to a
deadlock.
Fix this by unlocking peer_ref_mutex before calling
dp_reset_and_release_peer_mem().

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.

Observed that when IPA offload is enabled, RX packets
are not routed correctly to IPA ring. Currently only
IX0 of REO_DESTINATION_CTRL_IX registers are remapped,
which only covers 3-bit reo_destination_indication of
range 0 to 7.
Fix is to remap REO_DESTINATION_CTRL_IX2|3 registers
so that reo_destination_indication of range 16 to
31 can also be routed REO2IPA ring when IPA offload
is enabled. Upon IPA offload is disabled, save values
of IX2 and IX3 are reset back to HW.

If other core starts handling peer_unmap and holds vdev_list_lock

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.

Previously intra-bss fwd decision is done by FW and

WLAN driver. Now for WDI 3.0, FW is not involved in RX
path and SW path intra-bss fwd decision has to be done
in wlan driver.

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.

In some cases, the msdu_len as retrieved fromm msdu_start TLV is
greater than RX_BUFFER_SIZE. In such cases, when qdf_nbuf_set_pktlen
is called, it will expand the skb to accommodate the bigger packet.
This makes the rx_tlv_hdr var invalid, since it continues to point to
the older skb->data. Access of this rx_tlv_hdr will cause exception.
Drop the packet if msdu_len > RX_BUFFER_SIZE. This is not expected while
reaping WBM RX Release ring.
