Subject: dropbear: Add procd interface triggers when interface config is specified
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=16122117a5fb376bd5d5ed905a5eea9076d54b04;p=openwrt%2Fstaging%2Fdedeckeh.git

dropbear: Add procd interface triggers when interface config is specified

A dropbear instance having an interface config won't start if the interface is down as no
IP address is available.
Adding interface triggers for each configured interface executing the dropbear reload script
will start the dropbear instance when the interface is up.
