The whole CRC strip flag notion is backwards. 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?
