Hi Damjan, I have used below CLI's to create rdma interfaces over Mellanox , Can you suggest what set of CLi's I should use so that packets from rdma will also have mbuff fields set properly , so that we can directly right on KNI? create interface rdma host-if ens2f0 name device_9/0/0 create

2019-12-06 Thread Prashant Upadhyaya
Hi, I use VPP with DPDK driver for I/O with NIC. For high speed switching of packets to and from kernel, I use DPDK KNI (kernel module and user space API's provided by DPDK) This works well because the vlib buffer is backed by the DPDK mbuf (KNI uses DPDK mbuf's) Now, if I choose to use a native
