When MLX5 behaves in VF mode and the hypervisor have **trusted** this VF, to be able to receive specific traffic some requests must be done to configure the NIC. There is no API currently available to do it though Verbs, but there is in Linux side using Netlink.
The specific cases are: - Enable/disable promiscuous mode. - Enable/disable allmulti mode. - Add/remove mac addresses. Changes in v3: Add missing room to add the MAC address in the Netlink message. Changes in v2: Embed Netlink socket communication inside the PMD.
