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.

a7c21dc7f3 qcacmn: Allocate multi page memory for dp_rx_desc_pool_alloc
Allocate memory in multiple smaller chunks for dp_rx_desc_pool_alloc,
and link the pages instead of allocating one big contiguous memory to
avoid memory allocation failures.

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.

3f43a6924b qcacmn: Release SMMU IPA mappings after pipes are disabled
Currenlty RX buffer mappings to IPA domain are released when
REO2IPA ring are disabled but before IPA pipes are disabled.
There will be chances that IPA still accessing buffers with
mappings released, which could lead to SMMU fault.

Fix is to release SMMU mappings to IPA domain until IPA pipes
are disabled.

5a4530f824 qcacmn: Support WDI 3.0 SW path intra-bss forwarding
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.

cc43b53e87 qcacmn: Allocate IPA TX skb buffers with srng unlocked
On low memory system, skb allocation failures are observed in
dp_tx_ipa_uc_attach during driver loading phase. Per kernel
memory team analysis, failures are caused by large amount of
atomic allocations. Currently when allocating IPA TX skbs,
srng spinlock is first grabbed and then skb buffers are being
requested, which makes skb allocation happen in atomic context.

Fix is to make skb allocations with srng unlocked since it is
safe for race conditions during driver loading time. This ensures
skb allocations in process context.

443059e723 qcacmn: Set pcie addr flag for IPA rings
IPA driver adds is_txr_rn_db_pcie_addr and
is_evt_rn_db_pcie_addr in ipa_wdi_pipe_setup_info and
ipa_wdi_pipe_setup_info_smmu structure to check if doorbell
address is DDR address or PCIe memory mapped address. Thus
set the addr flag accordingly for IPA transfer and event
rings.

3b8104bdd3 qcacmn: Support WLAN IPA WDI 3.0 SMMU
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.

clients needs to be configured. In this change when IPA
uses GSI configure appropriate TX and RX clients/pipes.

81179cb75e qcacmn: Fixes for IPA enablement for lithium/Hastings
- Support to pass IPA enabled(disabled) flag from ini to DP layer
- Use ioremap call to translate tx_comp_doorbell_paddr obtained from
  calling ipa_setup api to tx_comp_doorbell_vaddr. This is needed to
  write the initial value of HP at the doorbell address.
- Change REO_DST_RING_SIZE and WLAN_CFG_TX_RING_SIZE to 1023
  for napier/hastings if IPA is enabled. This is needed because,
  ipa_setup API can handle only 16-bit values for the size param(bytes)
  of the ring.
- Disable hash based flow steering for SAP peers in case IPA is enabled
  and set default reo_dest_ring_4 as default RX ring. Since IPA will be
  reaping RX packets from reo_dest_ring_4 only, flow steering is not
  needed for SAP peers.
- Unmap pre-allocated TX buffers for IPA in the TX completion ring.
- Donot execute IPA functionality if IPA is disabled from ini.

be43d55622 qcacmn: Replace Linux Fix-Width data-type with C-99 stdints
Datapath supposed to be HLOS-agnostic, but there is some use of
Linux fixed-width types u8, u16, and u32. These should be replaced with
C99 fixed-width types uint8_t, uint16_t, and uint32_t so that they will
correctly be HLOS-agnostic and work on non-Linux targets.
