DEV_RX_OFFLOAD_KEEP_CRC offload flag added.
DEV_RX_OFFLOAD_CRC_STRIP flag will remain one more release but default
behavior in PMDs is to strip the CRC independent from this flag.
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 strip the CRC
