if NETWORKING_WITH_15_4_TI_CC2520

config	TI_CC2520_DEBUG
	bool "CC2520 driver debug"
	default n
	help
	  This option enables debug support for 802.15.4 CC2520 driver.

config TI_CC2520_DRV_NAME
	string "TI CC2520 Driver's name"
	default "cc2520"
	help
	  This option sets the driver name

config TI_CC2520_SPI_DRV_NAME
	string "SPI driver's name to use to access CC2520"
	default ""
	help
	  This option is mandatory to set which SPI controller to use in order
	  to actually control the CC2520 chip.

config TI_CC2520_SPI_FREQ
	int "SPI system frequency"
	default 0
	help
	  This option sets the SPI controller's frequency. Beware this value
	  depends on the SPI controller being used and also on the system
	  clock.

config	TI_CC2520_SPI_SLAVE
	int "SPI slave linked to CC2520"
	default 0
	help
	  This option sets the SPI slave number SPI controller has to switch
	  to when dealing with CC2520 chip.

config	TI_CC2520_FIBER_STACK_SIZE
	int "Driver's internal fiber stack size"
	default 640
	help
	  This option sets the driver's stack size for its internal fiber.
	  The default value should be sufficient, but it case it prooves to be
	  a too little, this option makes it easy to play with the size.

config	TI_CC2520_CHANNEL
	int "TI CC2520 Channel"
	default 26
	range 11 26
	help
	  All the 802.15.4 devices that want to connect to each other need
	  to have same channel. Default channel is 26.

config TI_CC2520_AUTO_CRC
	bool "Let the chip handling CRC on reception"
	default y
	help
	  When receiving a packet, the hardware can verify the CRC by itself
	  and will provide a flag letting know the success - or not - on
	  a flag on the footer.

config TI_CC2520_LINK_DETAILS
	bool "Forward RSSI and link information on reception to upper stack"
	default n
	select TI_CC2520_AUTO_CRC
	help
	  If necessary, it will be possible to grab link and RSSI information
	  from the packet footer and forward them to the above stack.

config TI_CC2520_AUTO_ACK
	bool "Let the chip handle TX/RX IEEE 802.15.4 ACK requests"
	default n
	select TI_CC2520_AUTO_CRC
	help
	  The chip is able to reply by itself to ACK requests as well as
	  waiting for an ACK when a TX packet is requesting an ACK. However,
	  this feature requires the chip to get hardware filtering on, and
	  thus the above stack needs to provide the right information for such
	  filtering feature to work.
