[dpdk-dev] [PATCH v3 1/7] ethdev: deprecate descriptor status check API

[Ferruh Yigit <ferruh.yigit@intel.com>]

Marking 'rte_eth_rx_descriptor_done()' API as deprecated.
``rte_eth_rx_descriptor_status`` and ``rte_eth_tx_descriptor_status``
APIs can be used as replacement.

Plan is to remove the API on 21.11 release.

v3:
* Just deprecating the 'rte_eth_rx_descriptor_done()' API without
  removing it to stick to the original plan.
