Description of problem:
1) It hardcodes devices in the ethX space. Network devices can have arbitrary names, and due to http://fedoraproject.org/wiki/Features/ConsistentNetworkDeviceNaming, will have
different names in Fedora 15.

3) It does all this by popen()ing ifconfig.
I would think this could be made a lot shorter, simpler, and more correct by just opening and reading /proc/net/dev.

PAPI isn't currently being built with any of the PAPI-C components, so this isn't visible in any of the executables in the package.
Hooray... so this can be closed? Or is the plan to enable these at some point?
This doesn't yield any problem executables because the PAPI-C components are
