| 2314 | Note 1: If "fullPowerReason" specificied in this API is set to |
| 2315 | eSME_FULL_PWR_NEEDED_BY_HDD, PMC will clear any "buffered wowl" requests |
| 2316 | and also clear any "buffered BMPS requests by HDD". Assumption is that since |
| 2317 | HDD is requesting full power, we need to undo any previous HDD requests for |
| 2318 | BMPS (using sme_RequestBmps) or WoWL (using sme_EnterWoWL). If the reason is |
| 2319 | specified anything other than above, the buffered requests for BMPS and WoWL |
| 2320 | will not be cleared. |
| 2321 | Note 2: Requesting full power (no matter what the fullPowerReason is) doesn't |
| 2322 | disable the "auto bmps timer" (if it is enabled) or clear any "buffered uapsd |
| 2323 | request". |
| 2324 | Note 3: When the device finally enters Full Power PMC will start a timer |
| 2325 | if any of the following holds true: |
| 2326 | - Auto BMPS mode is enabled |
| 2327 | - Uapsd request is pending |
| 2328 | - HDD's request for BMPS is pending |
| 2329 | - HDD's request for WoWL is pending |
| 2330 | On timer expiry PMC will attempt to put the device in BMPS mode if following |
| 2331 | (in addition to those listed above) holds true: |
| 2332 | - Polling of all modules through the Power Save Check routine passes |
| 2333 | - STA is associated to an access point |
| 2334 | \param hHal - The handle returned by macOpen. |
| 2335 | \param - enterWowlCallbackRoutine Callback routine invoked in case of success/failure |
| 2336 | \param - enterWowlCallbackContext - Cookie to be passed back during callback |
| 2337 | \param - wakeReasonIndCB Callback routine invoked for Wake Reason Indication |
| 2338 | \param - wakeReasonIndCBContext - Cookie to be passed back during callback |
