config WIFI_SILABS_SIWX91X_ADV_SCAN_THRESHOLD

	int "Advanced scan threshold (in dBm)"

	default -40

	help

	  Configure the default advanced scan threshold for WiFi scanning.

	  This value determines the signal strength (in dBm) below which

	  the advanced scan mechanism will be triggered. Adjust this value

	  to optimize scanning behavior based on your network environment.



config WIFI_SILABS_SIWX91X_ADV_RSSI_TOLERANCE_THRESHOLD

	int "Advanced RSSI tolerance threshold (in dBm)"

	default 5

	help

	  Configure the default RSSI tolerance threshold for advanced WiFi scanning.

	  This value determines the acceptable variation in signal strength (in dBm)

	  during advanced scanning. Adjust this value to fine-tune the sensitivity

	  of the scanning mechanism to signal fluctuations.



config WIFI_SILABS_SIWX91X_ADV_ACTIVE_SCAN_DURATION

	int "Advanced active scan duration (in ms)"

	default 15

	help

	  Configure the default advanced active scan duration for WiFi scanning.

	  This value determines the time (in milliseconds) spent on each

	  channel during an advanced active scan. Adjust this value to optimize

	  scanning speed and accuracy based on your network environment.



config WIFI_SILABS_SIWX91X_ADV_PASSIVE_SCAN_DURATION

	int "Advanced passive scan duration (in ms)"

	default 20

	help

	  Configure the default advanced passive scan duration for WiFi scanning.

	  This value determines the time (in milliseconds) spent on each

	  channel during an advanced passive scan. Adjust this value to optimize

	  scanning speed and accuracy based on your network environment.



config WIFI_SILABS_SIWX91X_ADV_MULTIPROBE

	int "Advanced multiprobe setting"

	default 0

	help

	  Configure the advanced multiprobe setting for WiFi scanning.

	  When set to 1, multiple probe requests will be sent to all access

	  points in addition to the connected SSID during scanning. Adjust

	  this value to fine-tune scanning behavior based on your network

	  requirements.



config WIFI_SILABS_SIWX91X_ADV_SCAN_PERIODICITY

	int "Advanced scan periodicity (in ms)"

	default 10

	help

	  Configure the default advanced scan periodicity for WiFi scanning.

	  This value determines the interval (in milliseconds) between consecutive

	  advanced scans. Adjust this value to balance scanning frequency

	  and power consumption based on your network environment.



config WIFI_SILABS_SIWX91X_ENABLE_INSTANT_SCAN

	int "Instant scan support"

	default 1

	help

	  Enable support to start an advanced scan immediately. When enabled, the device

	  can perform an advanced scan without waiting for the periodic

	  scan interval, enabling quicker detection of available networks.



# Override the WIFI_MGMT_SCAN_SSID_FILT_MAX parameter for the Wi-Fi subsystem.
