    MLNX_OFED and hard coded mac-addresses for VFs


      System: HP ProLiant m710p Server Cartridge

      OS: Ubuntu 16.04

      IB Controller: Mellanox Technologies MT27520 Family [ConnectX-3 Pro]



      Hi, I have networking booting system, all hardware nodes is booting from prebuild image.

      I installed MLNX_OFED driver with kernel modules inside base image, using this command:


      ./mlnxofedinstall --kernel 4.4.0-98-generic --without-dkms --add-kernel-support --without-fw-update


      Also I writed to /etc/modprobe.d/mlx4_core.conf:


      options mlx4_core num_vfs=1 port_type_array=2,2 probe_vf=1


      But after boot, and loading driver with this command


      /etc/init.d/openibd start


      Each my node have same mac-address on VF interfaces.

      Looks like MAC-addresses generates on the mlnxofedinstall step - this is wrong, it's should be generates automaticly when new VFs add, or save MAC-addresses somewhere in configuration, unlike be hardcoded somewhere in builded module.
