Currently g_instances_added is not decremented correctly
in scenarios where IPA callback fails. This prevents
freeing the g_ipa_config memory during deinit, causing a
memory leak. This change will ensure that the instance
count is decremented correctly as part of deinit
in both success and failure scenarios.

fails.

Below signature is seen in driver logs.
Target is suspended (via send_process_dhcp_ind_cmd_tlv:244)
cds_trigger_recovery_handler: critical host timeout trigger
fw recovery for reason code 34
Suspend/Resume test is run with SAP started and a ref-client
is associated with the SAP. One DHCP-Req packet is received
from ref-client before driver completes the resume process.
With SAP_DHCP_FW_IND feature enabled, driver will send one
WMI cmd to target for such DHCP packets received.
With IPA_OFFLOAD enabled, such DHCP packets are received from
the RX exception callback from IPA driver. Hence add support
to queue these DHCP packets onto pm_queue_head skb queue when
WLAN IPA component is still in suspended state. When IPA component
is resumed from suspend state, pm_queue_head skb queue will be
drained to pass up queued RX exception packets to stack.
For QCA_IPA_LL_TX_FLOW_CONTROL enabled platforms, such as WIN
chipsets, suspend/resume is not supported. Hence wrap fixes
only for !QCA_IPA_LL_TX_FLOW_CONTROL.

Currently IPA autonomy is disabled for opt wifi dp
feature inorder to set default packet routing
to HOST REO rings instead of IPA. The check currently
depends on the feature flag set from IPA.
But this does not handle the case if feature is
enabled from WLAN but disabled from IPA, as autonomy
will get enabled in this scenario and default packet
routing is set to IPA.
This fix will check if opt_wifi_dp feature is
enabled from WLAN and disable autonomy to
ensure the default routing is always set to
HOST REO rings.

This is a WAR to disable IPA offload during compile

This is a WAR, and will be fixed once a Kernel config is

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.

These filters help to determine which packets need

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.
