		config WIFI_SILABS_SIWX91X_ENABLE_ROAMING
		bool "WiFi roaming support"
		help
		Enable this option to configure roaming parameters.
		Roaming will be enabled automatically when the
		background scan is active, improving connectivity
		and performance during transitions between access points.

		config WIFI_SILABS_SIWX91X_ROAMING_USE_DEAUTH
		bool "Use deauth frames for roaming"
		depends on WIFI_SILABS_SIWX91X_ENABLE_ROAMING
		help
		Enable this option to allow roaming using
		deauthentication frames. By default, roaming
		is performed using Null data packets.

		depends on WIFI_SILABS_SIWX91X_ENABLE_ROAMING
		help
		Sets the default roam trigger level. Higher values trigger
		earlier roaming; lower values delay it. It determines
		when to start searching for a new AP.

		int "Default value of roam trigger level change (in dBm)"
		default 5
		range 0 90
		depends on WIFI_SILABS_SIWX91X_ENABLE_ROAMING
		help
		Configure the default trigger level change for WiFi roaming.
		This value determines the change in signal strength (in dBm)
		required to initiate a roaming event. A smaller value may result
		in more sensitive roaming behavior, while a larger value can
		reduce the frequency of roaming events. It determines
		the signal difference needed to switch to a new AP.
