Data Fields struct rte_ip_frag_death_row * dr rte_node_t node_id Detailed Description. I was wondering whether there were RX offload hardware that could (be programmed to) reassemble/reorder/batch several (already reassembled themselves ip+udp) packets together following a user-provided reassembly protocol, and if it was accessible through dpdk. librte_ip_frag – IP Fragmentation and Reassembly: Handles fragmentation and reassembly of IP packets, supporting both IPv4 and IPv6.

Each IP packet is uniquely identified by triple <Source IP address>, <Destination IP address>, <ID>. Packet fragmentation¶. If rte_eth_ip_reassembly_capability_get() returns 0, IP reassembly can be enabled using rte_eth_ip_reassembly_conf_set() and params values lower than capability params can be set in the PMD. To make ip_reassembly print the statistics to the standard output, the user must send either an USR1, INT or TERM signal to the process.

In case of IP reassembly offload failure, packet will be updated with dynamic flag - RTE_MBUF_DYNFLAG_IP_REASSEMBLY_INCOMPLETE_NAME and packets will be returned without alteration. For all of these signals, the ip_reassembly process prints Fragment table statistics for each RX queue, plus the INT and TERM will cause process termination as usual.
