	select NET_MGMT_EVENT
	help
	  Enable API that helps to create client/server network applications.
	  This API is experimental and subject to change.

config NET_APP_AUTO_INIT
	bool "Init networking support automatically during device startup"
	default y
	help
	  If this option is set, then the net_app API is automatically
	  initialized when the device is started. If you do not wish to do
	  this, then disable this and call net_app_init() in your application.

config NET_APP_INIT_TIMEOUT
	int "How long to wait for networking to be ready and available"
	default 30
	depends on NET_APP_AUTO_INIT
	help
	  The value is in seconds. If for example IPv4 address from DHCPv4 is not
	  received within this limit, then the net_app_init() call will fail
	  during the device startup.

	bool "This application wants IPv6 support"
	depends on NET_APP_AUTO_INIT
	select NET_IPV6
	help
	  The network application needs IPv6 support to function properly.
	  This option makes sure the network application is initialized properly
	  in order to use IPv6.

config NET_APP_NEED_IPV6_ROUTER
	bool "This application wants IPv6 router to exists"
	depends on NET_APP_AUTO_INIT
	depends on NET_IPV6
	help
	  The network application needs IPv6 router to exists before continuing.
	  What this means that the application wants to wait until it receives
	  IPv6 router advertisement message before continuing.

config NET_APP_NEED_IPV4
	bool "This application wants IPv4 support"
	depends on NET_APP_AUTO_INIT
	select NET_IPV4
	help
	  The network application needs IPv4 support to function properly.
	  This option makes sure the network application is initialized properly
	  in order to use IPv4.

	int "Number of simultaneous incoming connections"
	default 1
	depends on NET_APP_SERVER
	help
	  Tells how many simultaneous incoming connections the server instance can
	  support. The value of CONFIG_NET_TCP_BACKLOG_SIZE must be greater than
	  or equal to CONFIG_NET_APP_SERVER_NUM_CONN.

config NET_APP_CLIENT
	bool "Enable client support"
	default n
	help
	  Enables net app library client APIs.

config NET_APP_TLS

	default n
	depends on NET_TCP
	select MBEDTLS
	help
	  Enables net app library to use TLS for encrypted communication.

	bool "Enable DTLS support for UDP applications"
	depends on NET_UDP
	select MBEDTLS
	default n
	help
	  Enables net app library to use DTLS for encrypted UDP communication.

config NET_APP_DTLS_TIMEOUT
	int "DTLS session timeout"
	depends on NET_APP_DTLS
	default 15
	help
	  If a DTLS session does not have any activity, then disconnect
	  the session. The value is in seconds.

config NET_DEBUG_APP_TLS_LEVEL
	int "Debug level for mbedtls in net app library"
	depends on (NET_APP_TLS || NET_APP_DTLS) && NET_DEBUG_APP
	default 0
	range 0 4
	help
	  Sets log level for the mbedtls when debugging net_app library.
	  Levels are (from ext/lib/crypto/mbedtls/include/mbedtls/debug.h):
	  0 No debug
	  1 Error
	  2 State change
	  3 Information
	  4 Verbose

config NET_APP_TLS_STACK_SIZE
	int "TLS handler thread stack size"
	default 8192
	depends on NET_APP_TLS || NET_APP_DTLS
	help
	  TLS handler thread stack size. The mbedtls routines will use this stack
	  thus it is by default very large.

	depends on NET_APP
	help
	  Allow IP addresses to be set in config file for
	  networking client/server sample applications, or
	  some link-layer dedicated settings like the channel.
	  Beware this is not meant to be used for proper
	  provisioning but quick sampling/testing.
