Wifi usability: Change the unit of the threshold for tx/rx throughput from Mbps to Kbps
Data stall event can be triggered if the tx/rx tput is consecutively below a threshold over multiple RSSI polls. Changing the unit of the threshold from Mbps to Kbps allows us to configure a value below 1Mbps, e.g., 400Kbps.
