The current implementaion check for peer, vdev and pdev leaks on
psoc in order and if any leak is found for peer then QDF_DEBUG_PANIC
is called and vdev and pdev leaks are not checked. Similar is the case
if vdev leak is found, pdev leaks are not checked
Adding a wrapper API to check all the leaks and then do panic if any
leak is found

The printk buffer is protected by a global raw spinlock for readers
and writers. This restricts the contexts that are allowed to
access the buffer. So large latencies exists when printing to
kmsg done with QDF trace levels WARN, INFO, ERROR. This results
in roaming KPI for maximum transition time exceeding the expected
100ms.
So change info/err prints to debug prints in roaming path
to reduce delays in roaming time.

On rekey, the STA resets it’s PN to 0 but, the
AP sends out pending traffic with old PN values
before it resets the PN as well.
This causes traffic to stall and hence, TSC (transmit
sequence counter) should not be set to zero during rekey.
Instead, obtain last PN number for a non-bss peer while
configuring new key and pass the values to hostap.

In wlan_objmgr_get_vdev_by_macaddr_from_pdev driver checks the
first vdev matching the mac address and try to get ref and return
NULL if it fails.
In case if a vdev is logically deleted but not physically deleted
(some ref are pending) and a new vdev is added with same mac address
at the tail of the vdev list, the
wlan_objmgr_get_vdev_by_macaddr_from_pdev always return NULL cheking
for the logically deleted vdev, even when a valid vdev is present
after the logically deleted vdev.
Thus continue to next vdev if try get ref fails for the vdev.

SAE key derivation requires use of a secret element, PWE. This
element is deterministically discovered by repeatedly hashing
the password with some additional information until the
resulting hash is the abscissa of a point on the elliptic curve
(for ECC) or by exponentiating the hash digest to a constant to
produce an element (for FFC). This "hunting-and-pecking" loop
method is prone to side channel attacks.
To avoid this, a direct hashing to element technique in SAE is
introduced in IEEE P802.11-REVmd/D3.0. Support new RSNX IEEE
as part of the hash to element PWE derivation. The user space
sends the RSNX IE in the connect request.
Add support for new RSNX IE with element ID 244.

When moving a blocking command from pending to active queue,
we release the lock and call the activation cb.
After the activation cb returns, we update the blocking cmd
waiting flag based on the active cmd node's "is_blocking" param.
If the activation cb is also resulting in removing the command,
then after the cb returns, the active cmd node is returned to the
free pool and our check fails, and we miss to update the blocking
cmd waiting flag, resulting in no further commands moving to the
active queue.
The update to the blocking command should be done atomically,
immediately after it moves to active queue and before releasing
the lock for the activation callback.

In case vdev is logically deleted the serialization active timer fails
to start because it fails to get vdev ref count. Now in this case the
cmd is not removed from the active queue and is just marked
CMD_ACTIVE_MARKED_FOR_REMOVAL because CMD_MARKED_FOR_ACTIVATION is set.
Even during pdev stop as CMD_MARKED_FOR_ACTIVATION is set the command is
not removed.
Fix is to reset CMD_MARKED_FOR_ACTIVATION flag and handle it in same way
as the activate failure case.
Also reset the timer cmd after timer start failure to avoid vdev ref count
release by WLAN_SERIALIZATION_ID even when it failed to take the ref count
in first place.
