Do we really need to keep a eth_driver ?
As far as I can see, it is only a convenient wrapper for existing pci
drivers, but in the end it is just a pci_driver with ethdev context in
it that could be pushed to each existing driver.
In my initial description
http://dpdk.org/ml/archives/dev/2016-January/031390.html, what I had
in mind was only having a rte_eth_device pointing to a generic
rte_device.
If we need to invoke some generic driver ops from ethdev (I can only
see the ethdev hotplug api, maybe I missed something), then we would
go through rte_eth_device -> rte_device -> rte_driver.
The rte_driver keeps its own bus/private logic in its code, and no
need to expose a type.

Yes, that's the main change for me.
Thanks.
