Introducing KEEP_CRC in this release is OK, since no PMD announces this
capability, it should be safe.
Since many PMD's offloading patches are not applied yet, deciding on "Setting no
flag would mean stripping" helps to get this correct at first place for them.
Only this is ABI break, but I am not aware of any PMD that implements not
stripping CRC case so I hope this is acceptable.
If there is no objection, I will update notice to only remove flag in next release.
