gnrc_sixlowpan_frag_vrb_t *	gnrc_sixlowpan_frag_vrb_from_route (const gnrc_sixlowpan_frag_rb_base_t *base, gnrc_netif_t *netif, const gnrc_pktsnip_t *hdr)
	Generate reassembly buffer from a header's forwarding information.
void	gnrc_sixlowpan_frag_vrb_gc (void)
	Checks timeouts and removes entries if necessary.
gnrc_sixlowpan_frag_vrb_t *	gnrc_sixlowpan_frag_vrb_get (const uint8_t *src, size_t src_len, unsigned src_tag)
	Gets a VRB entry.
gnrc_sixlowpan_frag_vrb_t *	gnrc_sixlowpan_frag_vrb_reverse (const gnrc_netif_t *netif, const uint8_t *src, size_t src_len, unsigned tag)
	Reverse VRB lookup.
static void	gnrc_sixlowpan_frag_vrb_rm (gnrc_sixlowpan_frag_vrb_t *vrb)
	Removes an entry from the VRB.
static bool	gnrc_sixlowpan_frag_vrb_entry_empty (gnrc_sixlowpan_frag_vrb_t *vrb)
	Determines if a VRB entry is empty.
void	gnrc_sixlowpan_frag_vrb_reset (void)
	Resets the VRB to a clean state.
