{net,vdpa}/mlx5: Configure interface MAC into mpfs L2 table
commit 7c9f131 upstream. net/mlx5: Expose MPFS configuration API MPFS is the multi physical function switch that bridges traffic between the physical port and any physical functions associated with it. The driver is required to add or remove MAC entries to properly forward incoming traffic to the correct physical function. We export the API to control MPFS so that other drivers, such as mlx5_vdpa are able to add MAC addresses of their network interfaces. The MAC address of the vdpa interface must be configured into the MPFS L2 address. Failing to do so could cause, in some NIC configurations, failure to forward packets to the vdpa network device instance. Fix this by adding calls to update the MPFS table.
