[dpdk-dev] [PATCH 0/9] prepare for rte_device / rte_driver

[David Marchand]

Following discussions with Jan [1] and some cleanup I started on pci code,
here is a patchset that reworks pdev drivers registration and hotplug api.

The structures changes mentioned in [1] are still to be done, but at least,
I think we are one step closer to it.

Before this patchset, rte_driver .init semantics differed whether it
concerned a pdev or a vdev driver:
- for vdev, it actually meant that a devargs is given to the driver so
  that it creates ethdev / crypto objects, so it was a probing action
- for pdev, it only registered the driver triggering no ethdev / crypto
  objects

Patches 1 to 3 convert all existing pdev drivers into pci drivers and move
their registration in constructors.

Patch 4 might be of interest to Chelsio guys, following a regression they
reported [2].

Patches 5 and 6 align pci drivers and vdev drivers init.

Patches 7 to 9 move hotplug where it belongs.
I did not test patch 8 on FreeBSD (did not even compile it, for now).
