[v2,00/13] Implement new devargs framework

  Last release saw the introduction of the new devargs system.
To this end, the "class" abstraction was described as well
as a common API for querying and declaring devices.

This patchset implements the "eth" device class and the
query/declaration part of the framework for PCI and vdev buses,
enabling a minimal support for the new system.

A new testpmd command is added to test device querying.

Devargs parsing is extended in the relevant buses to test
device declaration. This part uses the new "rte_eth_dev_create" API,
introduced last release and used by only two PMDs, for now.

The new devargs format is also made available through the new --dev parameter.

Next work is to generalize use of new API for eth_dev creation,
compatibility layer for -w, -b and --vdev with --dev, and devargs unit test.

v2: fixed Andrew's and Stephen's remarks,
    added acks.

Gaetan Rivet (13):
  bus/pci: implement device iteration and comparison
  bus/pci: add device matching field id
  bus/vdev: implement device iteration
  bus/vdev: add device matching field driver
  ethdev: add private generic device iterator
  ethdev: register ether layer as a class
  ethdev: add device matching field name
  app/testpmd: add show device command
  bus/pci: pre-process declarative PCI devargs
  bus/vdev: pre-process declarative vdev devargs
  bus/pci: process declarative PCI devargs
  ethdev: process declarative eth devargs
  eal: add generic dev parameter

This part of the patchset is applied
(except patches 4 and 7 that were discussed).

This second part of the patchset is left for next release.

I think it's better to wait having the new devargs usable in these options,
so we will have more tests and feedbacks.

Summary: for 18.11, patches 1, 2, 3, 5, 6 are applied, thanks!
  

@Thomas Monjalon, Ping?. Some parts of this patch set was scheduled for 19.02.
