When WDS_EXT feature is enable, Host needs to redirect
the data packets to WDS extended netdevice.
Change is added the support for forwarding the RX packets
when received from IPA as an exception by deriving the
correct netdevice interface.

Currently soc->ipa_mapped flag is set to true only after all
the buffers are SMMU mapped to IPA. This leads to a race
window where Rx buffers routed to WLAN HOST in the replenish
path are not mapped to IPA, as the ipa_mapped flag is still
set to 0. The fix is to set the ipa_mapped flag to 1, right when
the IPA pipes are enabled, before waiting for the complete
buffer pool to be IPA SMMU mapped.
With this fix, RX buffers can be unmapped and mapped to IPA
domain in dp_pdev_rx_buffers_attach() and
dp_pdev_nbuf_alloc_and_map_replenish() in WLAN host RX path when
ipa pipes are enabled.
This change also renames ipa_mapped flag to ipa_map_allowed.

Two SMMU issues are seen on IPA domain with regard to RX.
1. map without unmap
2. Buffers not mapped into IPA.
With If198a6c5f22af58fdaf9d9c020c74b1f76002e37, mapping
RX buffers to IPA domain are deferred to IPA enable pipes
phase with soc->ipa_mapped flag check added. This leads
to a race window where RX packets are routed to WLAN Host
first with soc->ipa_mapped still being 0. In such case, RX
buffers handled by WLAN driver will neither unmap from IPA
domain nor map into IPA domain.
For !ipa_config_is_opt_wifi_dp_enabled(), fix is to set
soc->ipa_mapped to 1 earlier in soc attach phase instead of
IPA enable pipes phase. With this fix, RX buffers can be unmapped
from IPA domain and mapped to IPA domain in dp_pdev_rx_buffers_attach()
and dp_pdev_nbuf_alloc_and_map_replenish() in WLAN host RX path so
as to avoid above two SMMU issues.

Currently, IPA SMMU map/unmap is called as part
of init. This causes every nbuf to be mapped
to IPA in the Rx path, causing throughputs
to drop. This change resolves the problem by
deferring the IPA SMMU map/unmap
call to OPT_DP filter reserve/release, as
nbuf needs to be mapped to IPA only in this scenario.

access to pcie memory region is going in pcie_0 memory region.
IPA is not allowed to update 40th bit for any address given
from pcie_1 and pcie_2 memory region.
Fix is do not send the pcie update status as true to IPA for DB address,
so that IPA will take long path of mapping the address in smmu context and
then it will access the pcie region.

Inorder to keep the PCIe link up during
optional wifi dp transfer the
hif_force_wake_request() is called during
filter addition. This increments the rtpm_get counter.
Now if Wifi is disconnected before releasing the
filters, the corresponding hif_force_wake_release()
call is not made. This causes a mismatch in RTPM GET and
PUT calls and triggers an assert during hdd_wlan_stop_modules().
This change adds a cleanup call to release the force wake
and reduce the rtpm_put counter to prevent the assert.

This change adds the optional wifi datapath feature
to transfer data to and from modem via WLAN.
By using the existing path between WLAN and IPA, this
change registers new interfaces between IPA and WLAN
to reserve, add, delete and release rx filters,
which are required for setting up CCE filter rules.
These filters help to determine which packets need
to be routed to IPA specific REO rings.

In the case of MLO connection, MLD address is used for data
transmissions in the ethernet header. Take MLO-SAP intra-bss
forwarding as an instance, ref1 sends unicast arp-resp to
ref2 who initiates broadcast arp-req. DA and SA in the ethernet
header are both MLD mac addresses of ref1 and ref2.
Currently when WLAN IPA component does the intra-bss forwarding
check, MLO connection is not taken into consideration, where
only legacy hash table is searched. For a MLD peer, it is not
added into the legacy hash table but the MLD specific hash
table.
Hence in this change, use dp_peer_hash_find_wrapper() API with
CDP_WILD_PEER_TYPE to check if peer exists in both legacy
and MLD hash table.
