Macros
#define	CONFIG_GNRC_IPV6_EXT_FRAG_SEND_SIZE (1U)
	IPv6 fragmentation send buffer size.

#define	CONFIG_GNRC_IPV6_EXT_FRAG_RBUF_SIZE (1U)
	IPv6 fragmentation reassembly buffer size.

#define	CONFIG_GNRC_IPV6_EXT_FRAG_LIMITS_POOL_SIZE (CONFIG_GNRC_IPV6_EXT_FRAG_RBUF_SIZE * 2U)
	The number of total allocatable gnrc_ipv6_ext_frag_limits_t objects.

#define	CONFIG_GNRC_IPV6_EXT_FRAG_RBUF_TIMEOUT_US (10U * US_PER_SEC)
	Timeout for IPv6 fragmentation reassembly buffer entries in microseconds.

#define	CONFIG_GNRC_IPV6_EXT_FRAG_RBUF_DO_NOT_OVERRIDE
	Do not override oldest datagram when reassembly buffer is full.

Functions
gnrc_pktsnip_t *	gnrc_ipv6_ext_build (gnrc_pktsnip_t ipv6, gnrc_pktsnip_t next, uint8_t nh, size_t size)
	Builds an extension header for sending.

gnrc_pktsnip_t *	gnrc_ipv6_ext_process_hopopt (gnrc_pktsnip_t pkt, uint8_t protnum)
	Processes a packet's payload as hop-by-hop option if `protnum` is pointing to a value equal to PROTNUM_IPV6_EXT_HOPOPT.

gnrc_pktsnip_t *	gnrc_ipv6_ext_process_all (gnrc_pktsnip_t pkt, uint8_t protnum)
	Processes a packet's extension headers after a potential initial hop-by-hop header.
