Issue1: Driver RTPM state is ON/NONE, Kernel state is RESUMING.
cdp_runtime_resume is already complete,
hif_pm_runtime_get return -E_INPROGRESS,
dp_tx_hw_enqueue will set the flush event,
but cdp_runtime_resume is already done,
this flush event will be handled only on next pkt tx.
Issue2: Driver RTPM state: Resuming
hif_pm_runtime_get returns -EBUSY,
dp_tx_hw_enqueue is interrupted by any IRQ,
cdp_runtime_resume is completed,
dp_tx_hw_enqueue will set the flush event,
This flush event will be handled only on next pkt tx.
Fix:
Introduce a link_state_up atomic variable in hif to track the link state
change by pld_cb.
Set atomic variable link_state_up=1 in pmo_core_psoc_bus_runtime_resume
just after pld_cb. pld_cb brings the PCIe bus out of suspend state.
Set atomic variable link_state_up=0 in pmo_core_psoc_bus_runtime_suspend
just before pld_cb. pld_cb puts the PCIe bus into suspend state.
Introduce dp_runtime_get and dp_runtime_put.
dp_runtime_get get refcount with increment of an atomic variable.
dp_runtime_put return refcount with decrement of this atomic variable.
If hif_pm_runtime_get returns -EBUSY or -EINPROGRESS,
take the dp runtime refcount using dp_runtime_get,
check if the link state is up, write TX ring HP,
return the dp runtime refcount using dp_runtime_put.
cdp_runtime_suspend should reject the suspend, if dp_runtime_get is non
zero.
cdp_runtime_resume should wait until dp_runtime_get becomes zero or time
out, then flush pending tx for runtime suspend.

When runtime power management is enabled, until the system is fully
resumed, we do not post any message to CE, instead they will be queued
in HTC. Once the device is fully resumed, all HTT messages in the queues
will be downloaded to CE at once. In some corner cases, it is found that
too many FSE caches flush messages getting queued during the runtime
resume; once the device is fully resumed, all these would be downloaded
to the FW/HW at once causing unintended crashes.
Avoid posting FSE cache flush messages until the device is fully resumed
to fix the issue.

As part of the VoW IGMP improvements, which deals with
conversion of igmp packets to unicast packets, the
following changes are done when the new feature is enabled:
1. IGMP/MLD packets with special addresses (addresses not
part of any multicast group) will be converted to all
existing clients of the AP. These packets will be
directly fed to igmp multicast to unicast conversion
module.
2. The IGMP/MLD packets with group specific addresses will
first go to multicast enhancement module, where they
will be allowed to pass and will be converted to unicast.
3. The new feature will be enabled only when multicast
enhancement feature is enabled, which will be ensured
at the configuration level.
