+* 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
