between the VF representor and the VF or the parent PF. Those new fields
are to be included in ``rte_eth_dev_info`` struct.
+* 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
+
+* ethdev: Make CRC stripping default behavior in v18.05 without any flag
+ and remove flag completely in v18.08
+ ``DEV_RX_OFFLOAD_CRC_STRIP`` flag will be removed.
+
* i40e: The default flexible payload configuration which extracts the first 16
bytes of the payload for RSS will be deprecated starting from 18.02. If
required the previous behavior can be configured using existing flow
