Have you ever needed to get at some details about a network interface from inside a Ruby script, but got stuck trying to parse the output of ethtool? If so, you're one-in-a-million, but at least you don't have to write an ethtool parser any more. use Rethtool instead!

At present, Rethtool only supports a couple of things: * Retrieve various details about the interface (link speed, duplex, etc). * Determine if the link is currently up or down.

Adding extra SIOCETHTOOL features is relatively straightforward, thanks to cstruct and the base infrastructure already in place.
