| 2280 | * when it is time to generate the next beacon. |
| 2281 | * If gLimQuietState is not in the INIT state, then it |
| 2282 | * means that the next beacon may need to include some |
| 2283 | * information about the Quiet BSS IE. |

| 2285 | * state of gLimQuietState |
| 2286 | * |
| 2287 | *LOGIC: |
| 2288 | * This routine invokes schSetFixedBeaconFields() only |
| 2289 | * if necessary, as it is expensive to update the fixed |
| 2290 | * beacon fields during each beacon interval. |
| 2291 | * |
| 2292 | *ASSUMPTIONS: |
| 2293 | * This Quiet BSS IE will be sent out as part of |
| 2294 | * Proprietary IE's. If 802.11H is enabled, this IE |
| 2295 | * will be sent out as defined in the 11H spec |
