Currently a set of IPA2TCL and WBM2IPA rings is used for
IPA TX data path. Issue is when wlan is configured as
SAP-SAP DBS mode, slow 2G traffic will consume much more
TX resources and thus 5G traffic will have starvation,
which leads to severe degradation of DBS KPI.
Therefore separate IPA2TCL (SW2TCL2) and WBM2IPA (WBM2SW4)
rings are added to support alternative IPA TX pipe for 2G
traffic.

REO remap register direct writes as part of SAP stop could
result in a NOC error if the UMAC is in low power state.
Fix is to use shadow register writes for REO remap and
WBM HP registers.

Add apis to map generic registers to shadow region. Existing
logic includes mapping only srng based regs to the shadow
region.
Add support to map REO control regs and WBM2SW2 rel
ring HP reg address to the shadow region in case the direct
reg writes in IPA enable/disable autonomy fail due to UMAC
block being in a power collapsed state.
Shadow reg mapping for these regs is provided to FW during
init. Add stat shadow_reg_write_fail to track shadow reg
write failure and shadow_reg_write_succ to track successful
shadow writes.

A htt message arrived after ipa context is freed as part of
deinitialization which was dereferenced by event handler
assigned to pdev->ipa_uc_op_cb, resulting in crash.
To fix this, during deinit pdev->ipa_uc_op_cb is deregistered
and assigned NULL before freeing up ipa context.

During driver initialization, IPA TX and RX doorbell registers
are provided to wlan as physical addresses. With SMMU S1 enabled,
they're mapped to IOVA of wlan domain.
On driver deinit path, do smmu unmap for the two IOVA addresses.

Register IPA ready callback with IPA driver. The callback
sets ipa_is_ready flag in the host driver and kick starts
the ipa init sequence as part of which the Tx buffers are
mapped to IPA.
None of the IPA APIs are invoked until IPA ready registration
is complete.

Memory optimization of unused TX rings by not configuring rings that are
not being used. Configure 2 rings for host in the case of IPA, instead
of configuring 3. If IPA is disabled then configure only 1 set of TX
rings for host.

Currently cdp ops are given pdev/vdev/peer
handle as its arguments, which is directly
accessed in those APIs. This can cause a
race-condition in access of the respective
handles if it has been deleted in parallel.
Hence as a part of cdp convergence, pass only
the pdev_id or vdev_id or peer mac address,
which will be used to get the respective handles,
and hence avoiding the unwanted access of the
handles if it has been deleted.

Currently for REO reinject path, first fragment is in the
linear part of the skb buffer while other fragments are
appended to skb buffer as non-linear paged data. The other
point is that for REO reinject buffer, l3_header_padding is
not there, meaning ethernet header is right after struct
rx_pkt_tlvs.
Above implementation will have issues when WLAN IPA path is
enabled.
Firstly, IPA assumes data buffers are linear. Thus need to
linearize skb buffer before reinjecting into REO.
Secondly, when WLAN does IPA pipe connection, RX pkt offset
is hard-coded to RX_PKT_TLVS_LEN + L3_HEADER_PADDING. Thus
need to pad L3_HEADER_PADDING before ethernet header and
after struct rx_pkt_tlvs.

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.

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.

Support WDI 3.0 SW path intra-bss forwarding. Major
difference for WDI 3.0 is the metadata info passed
from ipa driver in skb->cb[].
Previously intra-bss fwd decision is done by FW and
it passes fw_desc to IPA where IPA driver passes onto
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.

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.
