61f47a6fbd qcacmn: Fix delay in driver logging
In function qdf_trace_msg_cmn va_end is called without va_start.
This can lead to delay in driver logging.

f72cbe544a qcacmn: populate NSS value and Translate MCS value for HT
This change will resolve displaying NSS value
in stats in case of HT. And also it will give
proper NSS value to calculate rate value. Modify MCS
value to match with Tx stats from firmware.

Also retain original MCS value to use in radiotap code
for HT case.

7c32e412b8 qcacmn: Add qdf_talloc APIs
Add APIs for t(ree) alloc(ated) memory management.

These APIs allocate memory like malloc, but track those allocations via
a parent-child relationship, or tree. If the parent is freed while it
still has children, a panic will be triggered. This effectively gives
you the ability to limit the lifetime of an allocation by ensuring the
child allocation lifetime will be strictly less than the parent
allocation lifetime.

bfd50437fd qcacmn: Use UNBOUND flag to create WMI RX workqueue
WMI RX workqueue is created with WQ_MEM_RECLAIM flag. When host receives
the WMI service ready event it queues the work. There is 50sec delay in
scheduling workqueue to process WMI service ready event. This results in
host timeout (timeout = 15sec) and wifi load failure. This cleans up the
host data structures related to data path. But work got scheduled after
50sec resulting in init path handling with inconsistent data structures.

Use workqueue UNBOUND flag to create WMI RX workqueue. Works queued to
unbound workqueues are implicitly HIGHPRI and dispatched to unbound
workers as soon as resources are available.

40bd452c5b qcacmn: Abstract qdf_mem_validate_list_node()
Currently qdf_mem contains a function, qdf_mem_validate_list_node(), for
validating a list node and ensuring it is currently part of a list.
Instead, abstract this function from qdf_mem, and move the definition to
qdf_list_node_in_any_list() in qdf_list. This is a more reasonable
location for the list-specific logic, and allows its reuse by other
callers.

0497d105b0 qcacmn: Panic before unlock on missing unmap
Currently, qdf_nbuf_map_check_for_leaks() logs the leak information
under spinlock before inducing a panic. This can cause a confusing false
positive panic upon releasing the spinlock if the logging took longer
than the spinlock timeout threshold. Since we already know we are going
to panic, panic under spinlock to ensure the panic message is always
appropriate.

Define qdf_aligned_mem_alloc_consistent() and qdf_aligned_malloc() which
allocates the memory and checks if allocated base address is aligned with
ring_base_align. If not, it frees the memory and re-allocates by adding
7 bytes to alloc_size and returns aligned address to the caller.

edd12697e4 qcacmn: Return success when debugfs is disabled
Currently, the QDF debugfs feature returns a no-support error code for
the init call when the feature is compiled out. Instead, return success
to avoid wlan load failure on some configurations and to make error
checking by the caller more straight forward under all configurations.

The deinit call also has the same problem, but none of the callers pay
attention to the return status. Additionally, the deinit function
returns success unconditionally when the feature is compiled in.
Rather than changing the return status to success when the feature is
compiled out, change the return type of the deinit function to void.
