Subject: Cancel (re)connect timer when deleting interface
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d4376788601c38963c4c836d325e3a66498079ea;p=project%2Fmdnsd.git

Cancel (re)connect timer when deleting interface

Firing timeout would cause a crash if interface has been deleted
meanwhile. The easiest way to trigger this was calling set_config ubus
method twice within 100 ms.
Cancel pending interface start before freeing it.
