Eric Badger 700c0e0f24 Don't require NIC devices to have specific PCI class
If a PCI node is the parent of a NIC, treat it as such, regardless of
the PCI class code for the device. This allows non-traditional devices
to act as NICs via the net plugin mechanism.

For consistency, treat GPUs similarly.
