* TODO: This thing must be rewritten. We really should have a struct with all the

* (domain:bus:device.function).
* This way we'll have ways to better organize the output, instead of relying
* on the order the information appears on lspci's output.
* Also, the "Resources" thing might be better implemented (and we won't need
* copies of information scattered everywhere like we do today).
