Re: [PATCH 07/15] eal: Make vdev init path generic for both virtual and physcial devices

I have some comments inline.

You should update the panic log here.

Same comment about "virtual device".

Should we keep this comment?

Should be _RTE_DEV_H_

Not only virtual.

[...]

You probably understood the idea ;)

Still "virtual" typo

Except typos, it seems a good step.
I think we could abstract more things in order to have even simpler API and 
simpler command line. But we'll see it in another step.
