It is sometimes useful to reverse map an errno into a QDF_STATUS. For
this purpose, introduce qdf_status_from_os_return(), the logical inverse
operation of qdf_status_to_os_return().

In P2P ROC and MGMT tx cases, it use kernel address as cookie and
provides to userspace. Which has security risk. Add QDF API for ID
allocation and map ID to pointer, provides ID to userspace instead
of kernel address.

In qdf_trace_hex_dump() API, linebuf array is not initialized where
it is used to print in the form of string in qdf_trace_msg() API,
this may cause information leak.
To address this issue, initialize the linebuf array to zero.

nbuf map tracking requires a bit of metadata which is currently
allocated dynamically for each mapping request. Change these allocations
to use a qdf_flex_mem pool instead, amortizing each physical allocation
over many mapping requests. This reduces the runtime overhead of the
nbuf map tracking feature, and provides significant memory savings when
MEMORY_DEBUG is also enabled.

It often happens that the WLAN driver needs to allocate some pool of
structures to handle bursty operations. The traditional approach is to
statically allocate the maximum number of structures that we want to be
able to handle concurrently. This has the significant down side of
requiring manual tuning for every hardware combination for optimal
behavior, and wasting large amounts of memory during non-burst periods.
Add a new flexible, segmented memory allocator in QDF to help address
such scenarios. A small static buffer segment is used to service the
vast majority of operations, while additional segments are dynamically
allocated as needed to meet demand. Critically, these additional
segments are freed when not in use to reduce memory consumption. The
result is a self-tuning buffer that combines most of the benefits of
pure dynamic allocation with most of the benefits of pure static
allocation.

While handling a multi-segment TSO packet, there is a race condition
where, if tx complete arrives fast enough, the un-sent TSO segments
may be lost forever and a previously sent segment would be attempted
to be sent over.

next entry.
