memory footprint which helps in better cache utilization when large number
of meter objects are used.
+* ethdev: The function ``rte_eth_dev_count``, often mis-used to iterate
+ over ports, is deprecated and replaced by ``rte_eth_dev_count_avail``.
+ There is also a new function ``rte_eth_dev_count_total`` to get the
+ total number of allocated ports, available or not.
+ The hotplug-proof applications should use ``RTE_ETH_FOREACH_DEV`` or
+ ``RTE_ETH_FOREACH_DEV_OWNED_BY`` as port iterators.

* ethdev, in struct ``struct rte_eth_dev_info``, field ``rte_pci_device *pci_dev``
replaced with field ``struct rte_device *device``.
