For WMI messages RTPM get is done during HTC message send and the
corresponding put is done in Tx failure or in Tx completion handler
for Tx success case. In the case where Tx completion is not received
for WMI messages RTPM put is not done as part of the cleanup which
results in RTPM Get and PUT call out of sync issues.
To fix the issue as part of HTC cleanup do RTPM put for WMI messages
for which tx completion is not received.

If SSR happens, before any tx_completion is received for
packets queued on copy-engine, there will not be any
tx completions received for these packets and should be
freed during de-init.
Currently the TxLookUpQueue is being flushed only for
WMI and HTC_CTRL endpoint only. HTT_DATA_SVC endpoint
also has interrupt based tx completion processing
enabled for certain targets, and the packets for this
endpoint are not being flushed during de-init.
Fix the above issue, by flushing the TxLookUpQueue for
HTT_DATA_SVC endpoint if interrupt based tx completions
has been enabled for this CE pipe.

Currently if the driver is in runtime suspend/suspending
state, any packet transmission will request for resume
via hif_pm_runtime_get.
Unfortunately there is a logging in the above API which
will lead to more time consumption in the NET_TX softirq
context. This can lead to other delay in processing other
softirqs in the system.
Fix this by skipping the logging in the packet transmission
path.

For HTT h2t message which has a response from FW, runtime
get is done in HTC layer and the corresponding runtime_put
is done as part of the HTT response processing. In a scenario
where the HTT response is not received from FW or not processed
by host, runtime_put is not done as part of cleanup and panic
is triggered due to get/put imbalance.
Fix is to do RTPM put as part of htc cleanup when the HTT
response from FW is not received or processed.

When packet tx fails at transport layer, packet is re-queued and given to

Since re-queuing is not fatal, it need not be printed on every attempt.

There might be a race condition between htc_kick_queues which is sheduled
by RPM resume and hdd_wlan_stop_modules.
Here are detail info:
1. Run time resume is called, which will schedule a work to do the
htc_kick_queues later.
2. hdd_wlan_stop_modules is called at the same time, which will call
htc_destroy to free the HTC_TARGET.
3. the htc_kick_queues will access the HTC_TARGET, but it has been
freed.

The htc connect message buffer is not unmapped,
if the firmware does not send wmi ready event to the
host.
Scenario:
- Host sends htc init command.
- The command is queued into the src ring.
- The firmware has crashed before the Copy Engine
could copy the message to the destination ring
- Due to the above point, no copy completion
interrupt is received.
- The host times out during its wait for the wmi
ready event.
- Hence the htc init command buffer stays unmapped
and unfreed.
As a part of the wma ready event missing cleanup,
the htc connect buffer is not unmapped. Fix this
to avoid missing to unmap the buffer.
To avoid a side effect of sending a completion for
HTC connect command, all the commands are freed in
the htc completion handler in case of SSR.

When the wlan driver is suspending, the last thing it does is check to
see if the firmware has indicated a wakeup during the suspend process.
This is done by checking the initial wakeup flag, which is set when a
specific copy engine payload is received from firmware. For the new
dedicated wake MSI, only the wake signal is received, no payload. When
the wake MSI is toggled, set the initial wakeup flag to prevent race
conditions during the suspend process.

Tx lookup queue holds the reference of the packet that is successfully
transmitted via CE pipe. Tx lookup queue method can be called from
tx path and from tasklet simultaneously for the same endpoint.
One context can get the packet reference in its local lookup Queue and the
other context may not find the reference as this is not brought back
from lookupQueue to TxLookupQueue.
