Note 1: If "fullPowerReason" specified in this API is set to
eSME_FULL_PWR_NEEDED_BY_HDD, PMC will clear any "buffered wowl"
requests and also clear any "buffered BMPS requests by HDD".
Assumption is that since HDD is requesting full power, we need to
undo any previous HDD requests for BMPS (using sme_RequestBmps) or
WoWL (using sme_EnterWoWL). If the reason is specified anything
other than above, the buffered requests for BMPS and WoWL
will not be cleared.
Note 2: Requesting full power (no matter what the fullPowerReason
is) doesn't disable the "auto bmps timer" (if it is enabled) or
clear any "buffered uapsd request".
Note 3: When the device finally enters Full Power PMC will start
a timer if any of the following holds true:
- Auto BMPS mode is enabled
- Uapsd request is pending
- HDD's request for BMPS is pending
- HDD's request for WoWL is pending
On timer expiry PMC will attempt to put the device in BMPS mode
if following (in addition to those listed above) holds true:
- Polling of all modules through the Power Save Check routine passes
- STA is associated to an access point
\param hHal - The handle returned by macOpen.
\param - enterWowlCallbackRoutine Callback routine invoked in case of

\param - enterWowlCallbackContext - Cookie to be passed back during

\param - wakeReasonIndCB Callback routine invoked for Wake Reason

\param - wakeReasonIndCBContext - Cookie to be passed back during callback
