DEV_RX_OFFLOAD_KEEP_CRC offload flag added. PMDs that supports keeping
CRC should advertise this offload capability.

DEV_RX_OFFLOAD_CRC_STRIP flag will remain one more release
default behavior in PMDs are to keep the CRC until this flag removed

Until DEV_RX_OFFLOAD_CRC_STRIP flag is removed:
- Setting both KEEP_CRC & CRC_STRIP is INVALID
- Setting only CRC_STRIP PMD should strip the CRC
- Setting only KEEP_CRC PMD should keep the CRC
- Not setting both PMD should keep the CRC

A helper function rte_eth_dev_is_keep_crc() has been added to be able to
change the no flag behavior with minimal changes in PMDs.

The PMDs that doesn't report the DEV_RX_OFFLOAD_KEEP_CRC offload can
remove rte_eth_dev_is_keep_crc() checks next release, related code
commented to help the maintenance task.

And DEV_RX_OFFLOAD_CRC_STRIP has been added to virtual drivers since
they don't use CRC at all, when an application requires this offload
virtual PMDs should not return error.

   - removal of ``txq_flags`` field from ``rte_eth_txconf`` struct.
   - removal of the offloads bit-field from ``rte_eth_rxmode`` 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.
