29 * This function resets the connection state.
30 *
31 * The function is invoked after receiving a disconnect event from firmware,
32 * and performs the following actions -
33 * - Set media status to disconnected
34 * - Clean up Tx and Rx packets
35 * - Resets SNR/NF/RSSI value in driver
36 * - Resets security configurations in driver
37 * - Enables auto data rate
38 * - Saves the previous SSID and BSSID so that they can
39 * be used for re-association, if required
40 * - Erases current SSID and BSSID information
41 * - Sends a disconnect event to upper layers/applications.
