why do you need to add a new option if you only insert a virtual
devargs?
Why wouldn't --vdev option work instead? and for that matter, I was
expecting you to provide a PCI address. Can you give a command line
showing how you create your device? The devtype is essentially ignored
currently (at option stage, maybe there are still cruft left in PCI bus),
instead the devargs parsing will detect the bus from the given optarg.
This part of EAL will change rather soon, I'd prefer not to deal with
additional options unless necessary.
