[PATCH v2 0/4] ethdev: rework config restore

[Dariusz Sosnowski]

This patch series reworks the config restore procedure,
so that drivers are able to enable/disable certain parts of it.
Drivers can provide get_restore_flags() callback,
which will indicate to ethdev library what configuration to restore.

If callback is not defined, then ethdev assumes that
all configuration must be restored, preserving the current behavior for all drivers.

This patch series also includes implementation of get_restore_flags()
for mlx5 PMD, which does not require config restore.
