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 v4: Track MAC addresses added by the PMD and not present in the bridge table to remove them when leaving. 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.
