Hello VPP experts, We have been using VPP with Mellanox ConnectX-5 cards for a while, which has been working great.
Now we have a new server where we want to run VPP in a similar way that we are used to, the difference is that the new server has ConnectX-6 cards instead of ConnectX-5. The lspci command shows each ConnectX-6 card as follows: 51:00.0 Infiniband controller: Mellanox Technologies MT28908 Family [ConnectX-6] Trying to create an interface using the following command: create int rdma host-if ibs1f1 name if1 num-rx-queues 4 gives the following error: DBGvpp# create int rdma host-if ibs1f1 name if1 num-rx-queues 4 create interface rdma: Queue Pair create failed: Invalid argument and journalctl shows the following: Nov 16 16:06:39 [...] vnet[3147]: rdma: rdma_txq_init: Queue Pair create failed: Invalid argument Nov 16 16:06:39 [...] vnet[3147]: create interface rdma: Queue Pair create failed: Invalid argument Nov 16 16:06:39 [...] kernel: infiniband mlx5_3: create_qp:3206:(pid 3147): Create QP type 8 failed We are using Ubuntu 22.04 and the VPP version tested was vpp v22.10. Do we need to do something different when using ConnectX-6 cards compared to the ConnectX-5 case? Best regards, Elias
