config WIRELESS_IEEE802154
	bool "IEEE 802.15.4 Wireless Support"
	default n
	select DRIVERS_IOB
	---help---
		Enables support for the IEEE 802.14.5 Wireless library.

menuconfig IEEE802154_MAC
	bool "Generic Media Access Control (MAC) layer for 802.15.4 radios"
	default n
	depends on WIRELESS_IEEE802154
	---help---
		Enables a Media Access Controller for any IEEE802.15.4 radio
		device. This in turn can be used by higher layer entities
		such as 6lowpan. It is not required to use 802.15.4 radios,
		but is strongly suggested to ensure exchange of valid frames.

config IEEE802154_MAC_DEV
	bool "Character driver for IEEE 802.15.4 MAC layer"
	default n
	depends on IEEE802154_MAC
	---help---
		Enable the device driver to expose the IEEE 802.15.4 MAC layer
		access to user space as IOCTLs

	---help---
		Work queue support is required to use the IEEE 802.15.4 MAC layer.
		If the low priority work queue is available, then it should be used by
		the driver.

config IEEE802154_IND_PREALLOC
	int "Number of pre-allocated meta-data structures"
	default 20
	---help---
		This specifies the total number of preallocated meta data structures
		must be allocated with each incoming packet.  These may be allocated
		from either from tasking logic or from interrupt level logic.

config IEEE802154_IND_IRQRESERVE
	int "Rserved pre-allocated meta-data structures"
	default 10
	---help---
		If meta-data structures can be allocated from interrupt handlers,
		then this specifies the number of pre-allocatd meta-data structures
		that are reserved for for use only by interrupt handlers.  This may
		be zero to reserve no meta-data structures for interrupt handlers.
		In that case, the allocation will fail if tasking logic has
		allocated them all.

		Interrupt logic will first attempt to allocate fromt the general,
		pre-allocated structure pool that will contain up to (size
		CONFIG_IEEE802154_IND_PREALLOC - CONFIG_IEEE802154_IND_IRQRESERVE)
		entries.  If that fails, then it will try to take a structure from
		the reserve (size CONFIG_IEEE802154_IND_IRQRESERVE).

		Non-interrupt logic will also first attempt to allocate fromt the
		general, pre-allocated structure pool.  If that fails, it will
		dynamically allocate the meta data structure with an additional cost in performance.

	bool "IEEE802154 6loWPAN Network Device"
	default n
	depends on NET_6LOWPAN && NET_IPv6

		Add support for the IEEE802.15.4 6loWPAN network device built on
		the common IEEE802.15.4 MAC.

		Work queue support is required to use the IEEE802.15.4 network
		driver.  If the low priority work queue is available, then it shoul
		be used by the loopback driver.
