Subject: interface: fix reload for devices that point to vlan aliases
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=c3bf8fd913a440b0711d48ea6b97e73e9a53a292;p=project%2Fnetifd.git

interface: fix reload for devices that point to vlan aliases

When aliases are derived from bridge-vlan section, the device lookup needs
to be repeated on reload.
