It is not directly related to the patch.
May be I miss something, but it looks like there is no way to say that
"I always strip CRC and cannot preserve it".

It looks like it is not 100% equivalent. As far as I can see dev_info
get does
not convert txq_flags to offloads in default_txconf and in any case
txq_conf.offloads
are overwritten here. So, if PMD provides default txq_flags, it is lost.
If it is intentionally, it should be highlighted and explained.
