It has been reported that memory corruption can occurred because network packages where received after EXIT_BOOT_SERVICES. See the thread starting at [1]. We try to remove all drivers when EXIT_BOOT_SERVICES is called. But * Some network drivers don't call their own stop method when removed. * Some network drivers don't have a remove method. * Some devices have CONFIG_DM_DEVICE_REMOVE=n. Let's call eth_halt() in EXIT_BOOT_SERVICES explicitly.
