Subject: interface: fix restart after reload with external devices
X-Git-Url: http://git.archive.openwrt.org/?p=project%2Fnetifd.git;a=commitdiff_plain;h=5844d3caa26f5f8810476836a8b711107e4ba8d7;hp=5844d3caa26f5f8810476836a8b711107e4ba8d7

interface: fix restart after reload with external devices

When an interface goes down, the main_dev is reset to NULL.
Track an externally added device separately to be able to bring it back
up.
