Hi,

     We are in developmental phase for 5G user plane as vpp.we are
struugling in measuring throughput in vpp.



40G traffic:



Using a Mellanox NIC created a RDMA interfaces , for 40G traffic Uplink
flow , facing a udp checksum drop in vpp.

The traffic drops at RDMA interfaces, and has a ”bad upd checksum” issue.



10G traffic:



Using a Mellanox NIC changed the 40G to 4x10 G in spirent and in NIC.
Created 4 SRIOV interfaces(as RDMA interface in vpp) .

But the packets are not reaching the SRIOV in vpp.



Kindly let us know how to proceed on this for 40G traffic flow.

Thanks in advance.



Regards,

Akash
