33 * For scan response error, the function cancels all the pending
34 * scan commands and generates an event to inform the applications
35 * of the scan completion.
37 * For Power Save command failure, we do not retry enter PS
38 * command in case of Ad-hoc mode.
40 * For all other response errors, the current command buffer is freed
41 * and returned to the free command queue.
