Hi Satya,
so this is obviously unfinished. Would you mind writing the code for that? You
just need to steal a piece of code from ip4_sv_reass.c to do that ;-) and then
steer your packets at custom node.
986 /* *INDENT-OFF* */
987 VLIB_REGISTER_NODE (ip4_sv_reass_custom_node) = {
988 .name = "ip4-sv-reassembly-custom-next",
989 .vector_size = sizeof (u32),
990 .format_trace = format_ip4_sv_reass_trace,
991 .n_errors = ARRAY_LEN (ip4_sv_reass_error_strings),
992 .error_strings = ip4_sv_reass_error_strings,
993 .n_next_nodes = IP4_SV_REASSEMBLY_N_NEXT,
994 .next_nodes =
995 {
996 [IP4_SV_REASSEMBLY_NEXT_INPUT] = "ip4-input",
997 [IP4_SV_REASSEMBLY_NEXT_DROP] = "ip4-drop",
998 [IP4_SV_REASSEMBLY_NEXT_HANDOFF] =
"ip4-sv-reassembly-handoff",
999
1000 },
1001 };
1002 /* *INDENT-ON* */
1003
1004 VLIB_NODE_FN (ip4_sv_reass_custom_node) (vlib_main_t * vm,
1005 vlib_node_runtime_t * node,
1006 vlib_frame_t * frame)
1007 {
1008 return ip4_sv_reass_inline (vm, node, frame, false /* is_feature */ ,
1009 false /* is_output_feature */ ,
1010 true /* is_custom */ );
1011 }
Thanks,
Klement
