When the PF (host port) is driven by DPDK (OVS-DPDK case), we face two different cases: - driver is bifurcated (Mellanox case), so the VF can be configured via the kernel. - driver is on top of UIO or VFIO, so DPDK API is required, and PMD-specific APIs were used. This new generic API will avoid vendors fragmentation. Some PMD-specific API could migrate to this generic model. As an example, the default MAC address configuration is demonstrated for a VF mapped to mlx5 representor port. As it breaks the ABI, I propose to merge this API in DPDK 19.11-rc2. I am sorry I had not send a patch since proposing a RFC in August.
