Well, the usb device drivers _do_ need individual suspend()/resume()
callbacks. The "new device model" stuff exists in part to ensure
that devices get those calls appropriately.
For example, suspending a bus-powered hub would need to morph into
disconnecting the devices it could no longer power ... and in your
case, suspending a network device that discards its firmware would
also need to morph into a disconnect.
