6c1cdf307a qcacmn: Fix memory leak in dp pdev attach failure case
Currently the failure in dp_rx_pdev_mon_attach, during
dp_pdev_attach_wifi3, does not cleanup the rx buffers
and hence that memory is leaked.

Follow the proper cleanup sequence to avoid leaking
the rx buffer memory.

3c91fb553a qcacmn: Set default REO destination ring to SW4
For MDM platforms, set default REO destination
ring to SW4 for STA vdev, which is same as SAP vdev.

Note that RX hashing is still enabled for STA vdev.
Also REO destination are run-time remapped when IPA
automony is enabled and disabled.

3f2ceb8b9f qcacmn: Fix deadlock due to peer_ref_mutex and scn_lock
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().

d8c7ad2228 qcacmn: Support per-ring CCE protocol tag stats
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.

09526ac0d1 qcacmn: Fix REO2IPA reo destination routing
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.

142f9baf47 qcacmn: Add new feature to support protocol tags
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.

0255314127 qcacmn: Check delete.pending in get_vdev_from_vdev_id
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.

Change some logging to dp_ logging functions.
