While Rx buffers are getting umapped from net rx context if IPA
pipes are enabled at same time from MC thread context this is
leading to race condition and IPA map/unmap is going out of sync.
To fix this introducing IPA mapping lock and IPA mapping need to
be handled with lock held.

It's regression of change: qcacmn: Fix smmu fault for tx buffer unmapped.
Only 1 tx buffer is smmu mapped for IPA with it.
During STA-SAP tethering, when IPA access 2nd tx buffer, smmu fault
happens.
Remove qdf_assert_always since it already exists in
__dp_ipa_handle_buf_smmu_mapping.

The status of the IPA SMMU MAP/UNMAP operation is stored in the
result field of the mem info structure that is passed to the
IPA driver. Currently, this field is not checked for MAP/UNMAP
failures; when IPA HW accesses such a buffer for which
mapping is not correctly setup, it will lead to SMMU faults.
Check the result and assert(on failures) to avoid such issues.
Also, check if the physical address passed to the IPA driver is
non zero value.

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.

Currently struct ipa_wdi_conn_in_params occupies 1588 bytes and putting
it on the stack is rather expensive, which could potentially lead to
stack corruption.
Fix is to reduce stack usage in dp_ipa_setup by dynamically allocating
struct ipa_wdi_conn_in_params on the heap.

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.

Currently when IPA is enabled, all RX frames will be routed to IPA
ring REO2SW4 by default, there is no REO2HOST option. once IPA RX/TX
is slow, then likely will give RX back pressure to wlan RXDMA. per
FW feature request, when IPA RX is slow or stuck, route RX frames to
wlan host to mitigate issue, thus provide REO2SW1 ring as REO_DST
option into HWIO_REO_R0_DESTINATION_RING_CTRL_IX_0.
To make sure if without FW dynamic REO_DST ring switching change,
current host change should not give chance that RX frames
route to host when IPA is enabled, select CTRL_IX_0 index 2 to
set REO_DST option, the reason is: if RX hash is enabled, CTRL_IX_2
and CTRL_IX_3 index 16~31 is REO_DST option filled with REO2SW4,
if RX hash is disabled, then CTRL_IX_0 index 1 and 4 filled with
REO2SW4 is REO_DST option configured by
WMI_HOST_PEER_SET_DEFAULT_ROUTING, so CTRL_IX_0 index 2
is only used for FW dynamic ring switching.

the ipa init sequence as part of which the Tx buffers are
