* on the station side, only call the quiet time IE method if we have a quiet IE - otherwise call the NULL method once, and then don't waste time calling NULL * on the beacon generation side - force a beacon regeneration each time quiet time is enabled/disabled. Without this, enabling/disabling quiet time IE would cause the beacon contents to be corrupted since none of the "move contents around" logic (like for CSA and TIM handling) is implemented. This changes the size of ieee80211_node so it requires a kernel recompile, but no userland recompile. Tested: * AR9380, AP mode, enabling/disabling quiet time IE * AR9380, STA mode, with upcoming driver changes.
