Functions | |
| void | gnrc_ipv6_ext_frag_init (void) |
| Initializes IPv6 fragmentation and reassembly. | |
| void | gnrc_ipv6_ext_frag_send_pkt (gnrc_pktsnip_t *pkt, unsigned path_mtu) |
| Send an IPv6 packet fragmented. More... | |
| void | gnrc_ipv6_ext_frag_send (gnrc_ipv6_ext_frag_send_t *snd_buf) |
| (Continue to) fragment packet already in fragmentation send buffer More... | |
| gnrc_pktsnip_t * | gnrc_ipv6_ext_frag_reass (gnrc_pktsnip_t *pkt) |
| Reassemble fragmented IPv6 packet. More... | |
| gnrc_ipv6_ext_frag_stats_t * | gnrc_ipv6_ext_frag_stats (void) |
| Get the current statistics on reassembly and fragmentation. More... | |
Reassembly buffer operations | |
| gnrc_ipv6_ext_frag_rbuf_t * | gnrc_ipv6_ext_frag_rbuf_get (ipv6_hdr_t *ipv6, uint32_t id) |
| Get a reassembly buffer by the identifying parameters. | |
| void | gnrc_ipv6_ext_frag_rbuf_free (gnrc_ipv6_ext_frag_rbuf_t *rbuf) |
| Frees a reassembly buffer entry (but does not release its gnrc_ipv6_ext_frag_rbuf_t::pkt) More... | |
| static void | gnrc_ipv6_ext_frag_rbuf_del (gnrc_ipv6_ext_frag_rbuf_t *rbuf) |
| Delete a reassembly buffer entry (and release its gnrc_ipv6_ext_frag_rbuf_t::pkt) More... | |
| void | gnrc_ipv6_ext_frag_rbuf_gc (void) |
| Garbage-collect reassembly buffer. More... | |
