- for each interface, read carrier info from sysfs into
args["{"..name.." carrier}"], 1 means 'link up', 0 'link down'
- the carrier info for the 'total' pseudo-interface is a logical or of
the carriers of the summed interfaces (i.e. those not contained in
the ignore list)
- sum rates of all interfaces (except the ones in an ignore list) and
make them available under the interfacename "total"
