Nowadays network interfaces have names like docker0, team0, ip_vti0, eno, wlp61s0 and so on. Including word "Interface" in beginning of graph_title groups these graphs together in web interface, not randomly before/after other network-graphs (ipconntrack, firewall, ...). See commit 70711831c44 in munin repository for similar change.

IMPORTANT: Since the data source for this plugin use 32bit counters, this plugin is really unreliable and unsuitable for most 100Mb (or faster) interfaces, where bursts are expected to exceed 50Mbps. This means that this plugin is usuitable for most production environments. To avoid this problem, use the ip_ plugin instead."
