net/mlx4: Implement promiscuous mode with device managed flow-steering
The device managed flow steering API has three promiscuous modes: 1. Uplink - captures all the packets that arrive to the port. 2. Allmulti - captures all multicast packets arriving to the port. 3. Function port - for future use, this mode is not implemented yet. Use these modes with the flow_attach and flow_detach firmware commands according to the promiscuous state of the netdevice.
