Many operations within the wlan driver occur in an asynchronous
manner. Requests are received by HDD via one of the kernel interfaces
(ioctl, nl80211, virtual file system, etc.). The requests are
translated to an internal format and are then passed to lower layers
for processing. For requests which require a response, that response
comes up from the lower layers in a separate thread of execution,
ultimately resulting in a call to a callback function that was
provided by HDD as part of the initial request. So a mechanism is
needed to synchronize the request and response.
Currently there are various mechanisms which perform these
synchronizations, but experience with them has revealed some flaws. So
a universal mechanism is needed to synchronize the request and
response which addresses all of the known flaws. This framework
provides that mechanism.

If the ROC is requested from the supplicant, the driver sends
scan request to the firmware. The driver start the timeout after
receiving ready on channel event from the firmware. While packet
transmission, if the channel is same and timer is not running,
the driver assumes that it is in the listen channel and thus
transmits the frame. But this condition even meets while the
driver waits for ready on channel event, and thus, it sends
the frame in the wrong channel.
The fix is to wait for the ready on channel event if the timer
is not running. The change also address that ROC is dequeued only
after cancel ROC is completed.

Currently in IBSSS mode, host do not change the peer state to
associate state after successful connection. Hence other
components always find peer state as not associate.
As a part of this fix, move IBSS peer state to associate state.

Object manager provides reference count infrastructure for all 4
common objects: psoc, pdev, vdev and peer. Reference count APIs
provide protection from use after free scenarios by making sure
reference counted object is not freed prematurely while its still
in use. Reference count usage requires certain set of disciplines
from components for example:
1) A component 'C' is responsible for all its reference count
2) A component 'B' can't release reference count of a common object
taken by component 'A'
3) A component can't release a reference count which it has not
taken.
Enable reference count debug infrastructure such that wrong APIs
usage can be detected and fixed properly.

In the case of concurrency, when the session decrements, the
opportunistic timer is started. After a while, when the
opportunistic time is expired, and the hw mode change for SMM
is issued, and the same time new interface comes up, then the
new forms MCC with the existing connection instead of forming
DBS.
The change is to avoid the race condition to form MCC instead of
DBS.

Remove all calls to cdp_remove_peers_for_vdev().
cdp_remove_peers_for_vdev() is called from vdev_resp_handler
to remove all vdev peers. All the peers associated with the vdev
are deleted before vdev stop and hence this call to
cdp_remove_peers_for_vdev() is redundant.
Delete only the self peer and remove the code to delete the
vdev peers.
