In STA+BT+BLE mode, we get expected wifi throughput numbers when BT device is not connected. However downlink throughput drops to 5-6 Mbps from 35+Mbps as soon as bluetooth keyboard is connected. [Fix] Enable UAPSD mode with some optimized parameters, so that wifi station can get Rx packets buffered by AP efficiently even if radio is shared with bluetooth [Test Case] Conducted throughput tests and confirmed throughput gets dropped by 60% to 65% as expected(not more than that) when bluetooth keyboard connected.
