Hi all, I noticed an issue when recalculating UDP checksums in dp_packet_ol_send_prepare -> packet_udp_complete_csum -> csum_finish. If the packet is the first fragment of a UDP fragmented packet, the checksum can be wrong. Example:UDP payload 2000 bytes, fragmented with MTU 1500. First fragment payload 1480 bytes, but udp->udp_len = 2008. Checksum calculation cannot access later fragments, so it’s incorrect. Has anyone seen this before or have a recommended solution for handling UDP checksum on fragmented packets? Thanks!
