So I think I have a good grasp of how to configure SR-IOV using Nvidia's guide here and I was able to show the VF's already. The only thing I can't get my head to wrap around on is step 7 under section 2 (Enable SR-IOV on the MLNX_OFED Driver). Why do you need to change the MAC address of every VF when I see that the individual VF's already have random MAC's assigned to them? Or is this just optional?
