[PATCH v4 0/8] fix hotplug API

[Gaetan Rivet <gaetan.rivet@6wind.com>]

Sending those fixes as separate patches as they stand on their own.
This series improves usability of the hotplug API and fixes a few issues
with existing implementations.

The hotplug API can be tested with the fail-safe PMD[1]. Its
documentation describes how to declare slaves and how to use it.

v2:

  - Add a new rte_devargs function taylored for hotplug operations.
    Upon device hotplug, the device is implicitly whitelisted.
    This configuration should supersede any previous existing bus
    configuration.
  - Merge hotplug add and remove fixes as they are now tied up.
  - Do not return an rte_device handle back from hotplug_add.

v3:

  - Further explain
      - the new rte_eal_devargs_insert function.
      - the hotplug add / remove fix
      - the PCI device name fix
  - Add comments to pci_name_set

v4:

  - Free rte_devargs after the device is being removed,
    to avoid risks of buses relying on the rte_devargs during the
    process.

Gaetan Rivet (8):
  vdev: implement plug operation
  devargs: introduce removal function
  devargs: introduce insert function
  eal: fix hotplug add / remove
  pci: use given name as generic name
  pci: fix generic driver pointer on probe error
  pci: fix hotplug operations
  bus: remove useless plug parameter
