@Rupesh, Thanks for the info. I am not too familiar with rdma interfaces, well at least the way vpp is utilizing them. It seems its polling the interfaces just like dpdk. I am also able to see traffic flowing through vpp, however its seems I can still interact with the ports via the kernel. This means that the interfaces are still being utilized by the kernel yes?
However my test traffic is flowing much more efficiently through the system than using just the interfaces with a basic linux kernel set up. I can only assume dpdk or rdma or a combination of both are being used properly. Matt was a great help and shared this link ( https://s3-docs.fd.io/vpp/22.10/developer/devicedrivers/rdma.html?highlight=rdma ) to documentation from vpp on rdma, however I would to read more about how the RDMA + DPDK system works. Do you have any other literature or documentation I can read? Also, unrelated question, it appears with startup.conf I can set the number of rx/tx ques and size, what is the default values for this? Does it use whatever ethtool -l and ethtool -g uses? Or do I need to set to maximums for those values to apply? I think its all working now, thanks again to all your help and quick responses :)
