The consequence, in the case of mlx5_vdpa, is the internal routing tables of the device are not updated and this can block the communication between two namespaces. To fix this problem, use virtnet_send_command(VIRTIO_NET_CTRL_MAC) to set the address from virtnet_probe() when the MAC address is not provided by the device. ==================== Link: https://lore.kernel.org/r/20230127204500.51930-1-lvivier@redhat.com Signed-off-by: Jakub Kicinski --- d8673afbf51036ed1d72d9828d0d679035bb0d54
