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.

	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.

		access to user space as IOCTLs

	depends on SCHED_WORKQUEUE
	---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.

	---help---
		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.
