Instead, just give it zeros and let it figure out what to do with them. Signed-off-by: Mitch Williams <mitch.a.williams@xxxxxxxxx> CC: Andy Gospodarek <andy@xxxxxxxxxxxxx> CC: Stefan Assmann <sassmann@xxxxxxxxx> Tested-by: Aaron Brown <aaron.f.brown@xxxxxxxxx> Tested-by: Stefan Assmann <sassmann@xxxxxxxxxx> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@xxxxxxxxx> So, for whatever reason we no longer assign a random MAC address when using the device in a VM (but we do still use one if attached to igbvf in the host). I expect we'll eventually see this on all the Intel SR-IOV NICs. The solution is to use the ip command to assign the VF a valid MAC address prior to using it with KVM. I'll let those who made the change defend it further if they wish. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
