Currently, there is a compilation error on the
OWRT SI in the alternate code path when optional
dp feature is not enabled.
The caller wlan_ipa_wdi_init_set_opt_wifi_dp() passes an
argument of incompatible type. This change fixes the
compilation issue.

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.

Current IPA/WLAN driver does not support the WDS feature.
Packets are dropped if they came via end-node which is not
in direct connection with root AP.

roaming, new src port learn case. Send WDS support to IPA
at wdi init and AP client connect event.

IPA driver is not able to deregister the netdev iface
as the WLAN driver is unregistering the netdev before
giving event to the IPA driver, hence IPA driver is unable
to map the local iface mapping.
FIX is to pass the netdev interface id to IPA driver
so that IPA can get the correct netdev.

After enable and disable of both radio, If second radio is enabled
then the instance_id from wlan driver is passed wrongly to IPA driver

With multiple radio supporting IPA offload path, the g_ipa_config

Spin_lock_bh is introduced in ipa wlan rx path by security fix

wlan_ipa_w2i_cb->cdp_peer_state_get->dp_get_peer_state->

put into backlog queue, net_rx soft irq is scheduled to handle it.
For each rx msdu, ipa rx work thread, net_rx soft irq and iperf/app
thread are scheduled, which make rx throughput failed to meet KPI.
To avoid spin_lock_bh, don't call cdp_peer_state_get for each rx pkt,
only call 1 time, and save peer auth state in IPA context, for following
pkts, just get peer auth state from IPA context without spin_lock_bh.

In dual SAP connection, calls only disable_pipes to disable IPA,
whereas during second SAP disconnection, to enable IPA, calls
wlan_ipa_uc_handle_first_con, which sends ipa_set_active MSG
as true to FW, for both Tx/Rx to resume.
So calling wlan_ipa_uc_handle_last_discon in dual SAP mode,
which sends ipa_set_active MSG as false to FW, to suspend.

Fix AP+AP IPA offload path failure when NAPI over IPA enabled on mdm
platforms by adding QCA_CONFIG_RPS check.
QCA_CONFIG_RPS is same as CONFIG_RPS, default Y, but depend on CONFIG_SMP
as msm-5.4/net/Kconfig.
For AP+AP mode,
For LA, CONFIG_SMP on, then QCA_CONFIG_RPS on, use IPA exception path.
For mdm, CONFIG_SMP off, then QCA_CONFIG_RPS off, use IPA offload path.
For IPA napi enable status check, just use qdf_ipa_get_lan_rx_napi,
don't need MACRO IPA_LAN_RX_NAPI_SUPPORT.

wlan_ipa_uc_loaded_uc_cb is an API that is registered to IPA driver.
Therefore when IPA uC is ready, IPA driver is likely to invoke this CB
into our driver. If it is invoked after a WLAN idle shutdown, ipa_obj
use-after-free will happen because ipa_obj is destroyed as part of
shutdown.
g_ipa_is_ready flag is cleared after ipa_obj is destroyed. Therefore
fix is to add a ipa_cb_is_ready check in wlan_ipa_uc_loaded_uc_cb to
ensure ipa_obj is allocated and not freed.

In the scenario where ipa connect pipes fails in the
wlan_ipa_uc_loaded_handler API, uc_loaded flag is not
reset. As a result of this, in wlan_ipa_uc_ol_deinit,
ipa_tx_buf_smmu_unmap and ipa_wdi_disconn_pipes APIs are
invoked incorrectly.
Fix is to set the uc_loaded flag to true only if connect
pipes and tx_smmu mappings are successful in
wlan_ipa_uc_loaded_handler. Also, initialize the uc_op_work
in wlan_ipa_uc_ol_init prior to the uc_loaded check to
avoid a possible race condition which could also result
in the similar issue as above.

During DUT STA Rx over IPA, qdf_spin_unlock_bh is called as following.

->cdp_ipa_rx_intrabss_fwd
->dp_ipa_rx_intrabss_fwd
->dp_vdev_get_ref_by_id
->qdf_spin_unlock_bh
netif_rx will raise NET_RX_SOFTIRQ in enqueue_to_backlog->
____napi_schedule even NAPI not enabled.
spin_unlock_bh will call do_softirq to execute NET_RX if NET_RX_SOFTIRQ
is raised.
If qdf_spin_unlock_bh is called in wlan_ipa_w2i_cb, once 1 skb received,
netif_rx is called, and NET_RX_SOFTIRQ and APP like iperf is scheduled,
too much context switch happens, CPU and power is wasted, Rx throughput
KPI failed on mdm platform which only has single 1.2G-1.5G CPU.
Fix it by avoiding intra bss forwarding for adapter in sta mode.
