And qemu should emulate this feature as you did: > > 1) get a random mac To me this looks like a spec violation. If the driver negotiates the VIRTIO_NET_F_MAC feature, the driver MUST set the physical address of the NIC to \field{mac}. Otherwise, it SHOULD use a locally-administered MAC address (see \hyperref[intro:IEEE 802]{IEEE 802}, ``9.2 48-bit universal LAN MAC addresses''). While not said explicitly, the assumption I think is that the local MAC is not a local one. > 2) advertise VIRTIO_NET_F_MAC > 3) set the random mac to vDPA through set_config that part looks wrong to me. Setting mac through set_config was a pre-virtio-1.0 way to send mac to device. In 1.0 we have VIRTIO_NET_CTRL_MAC_ADDR_SET for that: When using the legacy interface, \field{mac} is driver-writable which provided a way for drivers to update the MAC without negotiating VIRTIO_NET_F_CTRL_MAC_ADDR. > 4) advertise the random mac to emulated config to guest > > > > 2. mlx driver checks the mac address and if this mac is 0, return fail > > to qemu, but this need to change the UAPI. > > > uAPI is probably fine since ioctl can fail.  We can change the to allow the > set_config to fail but virito spec doesn't have a way to advertise the error > in this case.
