It really should of been a bit set if driver allows preserving CRC. Since changing the ABI is not possible right now; the ethdev core ought to log a warning whenever driver is registered without CRC_STRIP flag. Or is lack of CRC_STRIP in offload flags implying that driver can do strip and not stripping?
