Hello
=C2=A0
I hope this email finds you well. I have been successfully marking var= ious TCP/UDP flows using rte_flow. However, I have noticed that there are f= requent occurrences of checksum problems in the network. As a result, I wou= ld like to prevent flows with corrupted checksums (IP, TCP, UDP) that I mar= ked with rte_flow from reaching the application layer. However, I still wan= t to keep track of these flows and count the occurrences of IP, TCP, or UDP= checksum issues on a per-flow basis.

Is there a way to achieve this? I would like to have visibility into t= he number of checksum problems experienced by each flow (IP, TCP, UDP) with= out allowing them to reach the application layer.

I am currently using DPDK-23.03 and my network card is Mellanox MT2771= 0 Family [ConnectX-4]

Any guidance or suggestions you can provide on this matter would be gr= eatly appreciated.
