<pre wrap="">Occationally /proc/net/if_inet6 contains interface IDs with

This patch changes the evaluation so that fields are used instead
of the mere position by counting characters.
This is a backport from openwrt-routing and can be removed when
updating to OpenWRT 18.06, but not for newer versions of 17.01.
Fixes #98.
