You mean KEEP_CRC? I copy the flags from i40evf.
In release note:
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
