The layout has changed a little bit, but it's still parse-able by the
default tools.

A bigger issue is that in the fancy new late-Fedora/EL7 world, "ifconfig"
is deprecated (actually, it's apparently been deprecated for like a decade
in favor of 'ip', but I don't know anyone who doesn't use it) thanks to
the move away from SysV initscripts and is no longer installed by default.

Ensure that the "net-tools" RPM is installed if it isn't already; if you
have a blank ifstat section, this is most likely the case.
