config NET_OFFLOAD
	bool "Offload IP stack [EXPERIMENTAL]"
	default n
	help
	  Enables TCP/IP stack to be offload to a co-processor.

config NET_DEBUG_NET_OFFLOAD
	bool "Debug Net Offload Layer"
	default n
	default y if NET_LOG_GLOBAL
	depends on NET_LOG
	depends on NET_OFFLOAD
	help
	  Enables offload TCP/IP stack output debug messages.

config NET_L2_DUMMY
	bool "Enable dummy l2 layer"
	default n
	default y if !NET_L2_ETHERNET && NET_TEST
	help
	  Add a dummy L2 layer driver. This is usually only needed when
	  simulating a network interface when running network stack inside QEMU.

	  Enable Bluetooth driver that send and receives IPv6 packets,
	  does header compression on it and writes it to the
	  Bluetooth stack via L2CAP channel.

config NET_L2_BT_ZEP1656
	bool "***Workaround to work with Linux.***"
	depends on NET_L2_BT
	default n
	help
	  This workaround is necessary to interoperate with Linux up to 4.10 but
	  it might not be compliant with RFC 7668 as it cause the stack to skip
	  Neighbor Discovery cache causing the destination link address to be
	  omitted. For more details why this is needed see:
	  https://github.com/zephyrproject-rtos/zephyr/issues/3111

	help
	  Security level of Bluetooth Link:
	  Level 1 (BT_SECURITY_LOW) = No encryption or authentication required
	  Level 2 (BT_SECURITY_MEDIUM) = Only encryption required
	  Level 3 (BT_SECURITY_HIGH) = Encryption and authentication required
	  Level 4 (BT_SECURITY_FIPS) = Secure connection required
