/**
* @defgroup drivers_nrf51822_nrfmin NRF Minimal Radio Driver
* @ingroup drivers_netdev
* @brief Minimal driver for the NRF51822 radio
*
* This driver enables the use of the NRF51822 radio in a IEEE802.15.4 like
* fashion. In the current state, the driver is only be meant to be used with
* the netdev/netapi based network stack, while only being able to communicate
* with other NRF51822 devices using the same driver.
*
* The driver is using a Nordic proprietary physical layer, configured to for a
* bitrate of 2Mbit. The payload length is set to a maximum length of 250 byte.
* The proprietary frame format used has the following format:
*
* byte0 | byte1 - byte2 | byte3 - byte4 | byte5 byte6 | byte7 - byteN
* ------ | ------------- | ------------- | ------------- | -------------
* length | src_addr | dst_addr | proto | payload...
*
* An IEEE802.15.4 like behavior is reflected in the following way: the driver
* configures the radio device to use a fixed 5 byte addressing scheme. On this
* addresses, the first byte is set to a constant value, the same for all
* devices that use this driver. The next two bytes are set to the configured
* PAN ID, hereby simulating the use of PAN IDs. The last two bytes are set to
* a 16-bit short address, simulating IEEE802.15.4 short addresses.
*
* There is no support for EUIDs. Further there is no support for anything else
* than IEEE802.15.4 data frames, so no PAN coordinators, etc.
*
* The driver supports:
* - short address (16-bit)
* - using CPU-ID for default address
* - address broadcast (broadcast address is ff:ff)
* - PAN IDs (0 to 0xffff), PAN ID broadcast is not supported
* - setting of channel (0 to 0x3f)
* - setting of TX power (+4dBm to -20dBm)
* - packet type labeling
* - setting device state (RX, SLEEP)
