Deprecation Notices
-------------------
* The ethdev hotplug API is going to be moved to EAL with a notification
mechanism added to crypto and ethdev libraries so that hotplug is now
available to both of them. This API will be stripped of the device arguments
so that it only cares about hotplugging.
* Structures embodying pci and vdev devices are going to be reworked to
integrate new common rte_device / rte_driver objects (see
http://dpdk.org/ml/archives/dev/2016-January/031390.html).
ethdev and crypto libraries will then only handle those objects so that they
do not need to care about the kind of devices that are being used, making it
easier to add new buses later.
* The EAL function pci_config_space_set is deprecated in release 16.04
and will be removed from 16.07.
Macros CONFIG_RTE_PCI_CONFIG, CONFIG_RTE_PCI_EXTENDED_TAG and
