Macros
#define	CONFIG_GNRC_LWMAC_WAKEUP_INTERVAL_US (200LU *US_PER_MS)
	Time between consecutive wake-ups.

#define	GNRC_LWMAC_PREAMBLE_DURATION_US ((13LU * CONFIG_GNRC_LWMAC_WAKEUP_INTERVAL_US) / 10)
	The Maximum WR (preamble packet gnrc_lwmac_frame_wr_t) duration time.

#define	CONFIG_GNRC_LWMAC_TIME_BETWEEN_WR_US (5U *US_PER_MS)
	Timeout to send the next WR in case no WA has been received during that time.

#define	GNRC_LWMAC_WAKEUP_DURATION_US (CONFIG_GNRC_LWMAC_TIME_BETWEEN_WR_US * 2)
	How long a node in LWMAC should keep awake and listen on the channel in one cycle.

#define	GNRC_LWMAC_BROADCAST_DURATION_US ((CONFIG_GNRC_LWMAC_WAKEUP_INTERVAL_US * 11) / 10)
	How long broadcast packets gnrc_lwmac_frame_broadcast_t will be sent to make sure every participant has received at least one copy.

#define	GNRC_LWMAC_TIME_BETWEEN_BROADCAST_US (CONFIG_GNRC_LWMAC_TIME_BETWEEN_WR_US)
	Time to idle between two successive broadcast packets, referenced to the start of the packet.

#define	CONFIG_GNRC_LWMAC_WR_PREPARATION_US ((3U *US_PER_MS))
	WR preparation overhead before it can be sent (higher with debugging output).

#define	CONFIG_GNRC_LWMAC_DATA_DELAY_US (10U *US_PER_MS)
	How long to wait after a WA for data to come in.

#define	CONFIG_GNRC_LWMAC_DATA_CSMA_RETRIES (3U)
	CSMA retries for DATA packet after WR->WA was successful.

#define	CONFIG_GNRC_LWMAC_MAX_DATA_TX_RETRIES (3U)
	Maximum TX transmission retries for DATA packet in case of no response from the receiver.

#define	GNRC_LWMAC_MAX_TX_BURST_PKT_NUM (CONFIG_GNRC_LWMAC_WAKEUP_INTERVAL_US / GNRC_LWMAC_WAKEUP_DURATION_US)
	MAX burst transmission packet number in one shot.

#define	CONFIG_GNRC_LWMAC_MAX_RX_EXTENSION_NUM (3U)
	MAX bad Listen period extensions a node can tolerate.

#define	CONFIG_GNRC_LWMAC_BROADCAST_CSMA_RETRIES (3U)
	CSMA retries for broadcast packet.

#define	CONFIG_GNRC_LWMAC_RADIO_REINIT_THRESHOLD (10U)
	Maximum preamble attempts before re-initialize radio in LWMAC.

Functions
int	gnrc_netif_lwmac_create (gnrc_netif_t netif, char stack, int stacksize, char priority, const char name, netdev_t dev)
	Creates an IEEE 802.15.4 LWMAC network interface.
