* ethdev: A new offloading flag ``DEV_RX_OFFLOAD_KEEP_CRC`` will be added in v18.08,
This will replace the usage of not setting ``DEV_RX_OFFLOAD_CRC_STRIP`` flag
and will be implemented in PMDs accordingly.
In v18.08 both ``DEV_RX_OFFLOAD_KEEP_CRC`` and ``DEV_RX_OFFLOAD_CRC_STRIP`` flags
will be available, usage will be:
``CRC_STRIP``: Strip CRC from packet
``KEEP_CRC``: Keep CRC in packet
Both ``CRC_STRIP`` & ``KEEP_CRC``: Invalid
No flag: Keep CRC in packet
* ethdev: In v18.11 ``DEV_RX_OFFLOAD_CRC_STRIP`` offload flag will be removed, default
behavior without any flag will be changed to CRC strip.
To keep CRC ``DEV_RX_OFFLOAD_KEEP_CRC`` flag is required.
``KEEP_CRC``: Keep CRC in packet
No flag: Strip CRC from packet

``rte_eth_dev_filter_supported()``, ``rte_eth_dev_filter_ctrl()`` as well
