[RFC v3 0/7] Rework device probing

[David Marchand]

Applications relying on device hotplug don't work well with the default
probing of all available resources.
This series proposes to change this behavior via a new EAL option.

Changes since RFC v2:
- went one step further and reworked devargs lookup in buses following
  Bruce comment (see patch 4 which is cosmetic, and patch 5),
- updated device selection helper accordingly and
  changed API to be device name based,
- renamed option, added check on -b presence, updated doc in the last
  patch,

Changes since RFC v1:
- reviewed bus probe() and cleaned up NXP drivers,
- changed approach following Bruce comment,

David Marchand (7):
  devtools: check packet forwarding in null test
  bus/fslmc: fix bus cleanup
  drivers/bus: require probe function for NXP drivers
  drivers: cleanup devargs lookup in bus scan
  bus: factorize devargs lookup
  bus: factorize device selection
  eal: configure initial device probing
