Hi, I'm looking for best practice or experience on running OVS-DPDK and other kernel based applications with the same interface especially with MLX5 PMD. As long as I know, one of both must use VF and the other use PF since kernel and DPDK cannot bind to same interface. Which one of following is possible and better? 1. OVS-DPDK bind to PF and kernel bind to VF 2. OVS-DPDK bind to VF and kernel bind to PF If it is better (or the only possible) to use No. 2, what version of OVS and DPDK support VF binding? Should I bind to kernel created VF directly or it's representor?
If you use option 2 then the Linux kernel has PCI-e primitives that support the allocation of the VF resources, including number of VFs, their permissions and settings of any offload capabilities that the VFs might have.
