 *	Increase the SURVEY_TO value from 100 to 150  ( 100ms to 150ms )
 *	The Realtek 8188CE SoftAP will spend around 100ms to send the probe response after receiving the probe request.
 *	So, this driver tried to extend the dwell time for each scanning channel.

 * Usage:
 * When one iface acted as AP mode and the other iface is STA mode and scanning,
 * it should switch back to AP's operating channel periodically.
 * Parameters info:
 * When the driver scanned RTW_SCAN_NUM_OF_CH channels, it would switch back to AP's operating channel for
 * RTW_BACK_OP_CH_MS milliseconds.
 * Example:
 * For chip supports 2.4G + 5GHz and AP mode is operating in channel 1,
 * RTW_SCAN_NUM_OF_CH is 8, RTW_BACK_OP_CH_MS is 300
 * When it's STA mode gets set_scan command,
 * it would
 * 1. Doing the scan on channel 1.2.3.4.5.6.7.8
 * 2. Back to channel 1 for 300 milliseconds
 * 3. Go through doing site survey on channel 9.10.11.36.40.44.48.52
 * 4. Back to channel 1 for 300 milliseconds
 * 5. ... and so on, till survey done.
