qdf_mem_malloc/free wrappers are using ksize to update the kmalloc counters
of the driver whereas the debug versions of this wrappers are using
requested size itself. To figure out the actual dynamic memory held by
the driver on the debug profile, use ksize for debug versions as well.

This change adds support for driver supported TCP
delayed ack to increase TCP RX performance in
third-party platform which don't support kernel
TCP delayed ack feature.
TCP delayed ack is dependent on count and timer
values. Whatever is achieved first will trigger
sending TCP ack.
This feature can be controlled through ini values.
gDriverDelAckTimerValue - timer value in ms
gDriverDelAckPktCount - delayed ack count
gDriverDelAckEnable - enable/disable feature

Mc timer is used to initialize the p2p roc timer.
And the actual timer runs in the soft irq thread and
when the timer exipres it posts the message to mc thread.
Currently, qdf_mc_timer_stop is called to stop the timer.
It calls the del_timer internally to delete the timer.
del_timer() ensures that the given timer is not queued
to run anywhere in the system. But the callback may
be running on another CPU core can create race conditions.
So use del_timer_sync to delete the roc timer.

With this feature, using appropriate commands, link layer, network layer,
transport layer and some of the application protocols can be tagged with
the user provided tag values for easier identification of protocols. The
supported protocols today are as follows.
ARP, DHCPv4, DHCPv6, DNS over TCP (v4), DNS over TCP (v6), DNS over UDP
(v4), DNS over UDP (v6), ICMPv4, ICMPv6, TCPv4, TCPv6, UDPv4,
UDPv6, IPv4, IPv6, EAP.
Receive packets are tagged by hardware. Tags are applied after the first
matching rule. Hence it is recommended that the rules are
programmed in such a way that tags are configured from application layer
to data link layer to get expected results.

A common problem in any C code base is the proper management of various
resources, such as memory allocations, timers, works, locks, etc. To
that end, WLAN has added various one-off leak tracking features for
different resources over the years, to great benefit. However, this
approach is tedious, and prone to copy/paste and fix propagation issues,
making maintaining these various tracking features onerous.
Add a generic leak tracking data structure to WLAN for general use,
which implements these tracking logics. This will allow the various
resource tracking features to leverage this shared implementation for
ease of maintenance. Build on the hash table implementation added as
part of I7f5fc0c59ed220bde43044e7013b3c8573f1bf39.

While the Linux kernel provides a generic hash table data structure, it
makes the assumption that it will always be referred to statically, so
as to avoid having to store the size of the hash table's internal array.
This limitation means reusing this data type generically is difficult or
impossible.
Add a very simple hash table implementation to WLAN for general use,
which stores its own size information, and assumes all input keys will
be pointers. Build on top of the recently added single-linked list
implementation added in I2959f34649a0d8e0b312d9d67c81de17753b9b6c to

Due to a limitation in the memory leak detection logic when qdf_flex_mem
was written, qdf_flex_mem_release() was necessary to free any
dynamically allocated memory in the qdf_flex_mem_pool during certain
points in the WLAN driver lifecycle. This was done to avoid flagging any
dynamically allocated qdf_flex_mem_segments as false positive leaks
when the memory domains were changed and leak checking was performed.
With the introduction of qdf_talloc(), this workaround is no longer
required. Replace the calls to qdf_mem_malloc/free with qdf_talloc/free,
and remove qdf_flex_mem_release() altogether.

qdf_timer_t has repeatedly been identified as a problem area by Control-
Flow Integrity (CFI) analysis. This is because qdf_timer_init casts the
callback from a signature taking a "void *" into one which takes an
"unsigned long." While this "works," it is technically undefined
behavior, and CFI is correct in flagging it. Unfortunately, CFI
indicates the issue is with the callbacks themselves, which is incorrect.
Using unsigned long as the callback parameter has a number serious
drawbacks. Most significant is the fact that pointer size is not
guaranteed to be the same size as an unsigned long on platforms other
than Linux. For example, this is not the case on 64 bit Windows. As QDF
is supposed to be a platform abstraction, it cannot use unsigned longs
for memory addresses.
Instead of casting the timer callback in qdf_timer_init, use a callback
shim which takes an unsigned long, and handles the appropriate
conversions needed to call the actual callback function.

A common pattern in WLAN to panic the driver is to log the reason and
then unconditionally panic. QDF_DEBUG_PANIC() takes a reason string to

used. Ensure all callers of QDF_DEBUG_PANIC() provide a reason string.
Additionally, make the reason string parameter of QDF_DEBUG_PANIC()
