7147b3ccbf qcacmn: RX optimization changes to reduce cache misses
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

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.

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.

5679e39c7d qcacmn: Fix RX buffers refill for driver loading
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.

  destination ring via rx_buf_cookie (dp_rx_process). Add stats.
- Check if we end up re-using a rx_desc with rx_desc.in_use=1 in the

- Drop RX packet and assert in case MSDU Done failures are seen in
  in the TLV during dp_rx_process. Add stats.

  receiving these interrupts.

Support WLAN IPA WDI 3.0 with SMMU-S1 enabled. Key design
considerations are captured below.

- ring base addresses are passed as struct sg_table and IPA
driver will do the IOVA mapping to IPA domain.
- ring doorbell addresses are passed as physical address and
IPA driver will do the IOVA mapping to IPA domain.
- TX/RX buffers need to be mapped to IPA domain by WLAN driver
via ipa_wdi_create|release_smmu_mapping API.
- IPA doorbell addresses returned from ipa_wdi_conn_pipes are
DDR addresses and WLAN driver needs to do the IOVA mapping
to WLAN domain.

Currently wds enable for vdev conditional check is there for
intra bss rx forward. This check will break the intra bss for
the platforms which does not support WDS feature. In this change
remove the wds enable check for dp vdev.
