Macros
#define	GNRC_SIXLOWPAN_FRAG_SFR_CONGURE_UNIT   (1U)
	The user-defined window unit for congure is one fragment with SFR.

Functions
congure_snd_t *	gnrc_sixlowpan_frag_sfr_congure_snd_get (void)
	Retrieve CongURE state object from a pool of free objects.
static void	gnrc_sixlowpan_frag_sfr_congure_snd_free (congure_snd_t *c)
	Frees the CongURE state object.
static void	gnrc_sixlowpan_frag_sfr_congure_snd_destroy (gnrc_sixlowpan_frag_fb_t *fb)
	Frees the CongURE state object of a fragmentation buffer and set's it to NULL
static void	gnrc_sixlowpan_frag_sfr_congure_snd_init (gnrc_sixlowpan_frag_fb_t *fb)
	Initializes a CongURE state object in a fragmentation buffer entry.
static void	gnrc_sixlowpan_frag_sfr_congure_snd_setup (gnrc_sixlowpan_frag_fb_t *fb)
	Retrieve CongURE state object when not retrieved and initialize it for a fragmentation buffer entry.
static bool	gnrc_sixlowpan_frag_sfr_congure_snd_in_cwnd (gnrc_sixlowpan_frag_fb_t *fb)
	Checks if given fragmentation buffer entry is within congestion window.
static bool	gnrc_sixlowpan_frag_sfr_congure_snd_next_in_cwnd (gnrc_sixlowpan_frag_fb_t *fb)
	Checks if given fragmentation buffer entry would still be within congestion window after next send.
static bool	gnrc_sixlowpan_frag_sfr_congure_snd_has_inter_frame_gap (void)
	Checks if inter-frame gap is provided.
static uint32_t	gnrc_sixlowpan_frag_sfr_congure_snd_inter_frame_gap (gnrc_sixlowpan_frag_fb_t *fb)
	Returns inter-frame gap if provided by CongURE implementation.
static void	gnrc_sixlowpan_frag_sfr_congure_snd_report_frag_sent (gnrc_sixlowpan_frag_fb_t *fb)
	Report to CongURE that a fragment was sent.
static void	gnrc_sixlowpan_frag_sfr_congure_snd_report_frag_discard (gnrc_sixlowpan_frag_fb_t *fb)
	Report to CongURE that a fragment as discarded.
static void	gnrc_sixlowpan_frag_sfr_congure_snd_report_frags_timeout (gnrc_sixlowpan_frag_fb_t *fb)
	Report to CongURE that the ACK for a fragment timed out.
static void	gnrc_sixlowpan_frag_sfr_congure_snd_report_frags_lost (gnrc_sixlowpan_frag_fb_t *fb, congure_snd_msg_t *frags)
	Report to CongURE that a number of fragments are known to be lost.
static void	gnrc_sixlowpan_frag_sfr_congure_snd_report_frag_acked (gnrc_sixlowpan_frag_fb_t *fb, congure_snd_msg_t *frag, congure_snd_ack_t *ack)
	Report to CongURE that a number of fragments are known to be lost.
static void	gnrc_sixlowpan_frag_sfr_congure_snd_report_ecn (gnrc_sixlowpan_frag_fb_t *fb, uint32_t time)
	Report to CongURE that ECN bit was set in an ACK.
