If there are network devices that could probe without some of their suppliers probing and those network devices are needed to mount a network rootfs, then fw_devlink=on might break that usecase by blocking the network devices from probing by the time IP auto config starts. So, if no network devices are available when IP auto config is enabled and we have a network rootfs, make sure fw_devlink doesn't block the probing of any device that has a driver and then retry finding a network device.
