From: Raja Mani <rmani@xxxxxxxxxxxxxxxx>
* In order to save the target power in WOW suspend state,
configure the best optimal values for the below parameters,
- listen interval.
- beacon miss interval.
- scan parameters.
Default values for above attributes are reverted in
wow resume operation.
* The default listen interval is set before the host issue
connect request.
* New function is added to configure beacon miss count.
