> For hns3 NIC, when KEEP_CRC offload is enabled, the CRC data is still be stripped in rare scenarios.
> Some users of hns3 are already using this feature. So driver has to recaculate packet CRC.
>
> In addition, in the mbuf, the data that exceeds the length specified by pkt_len is invalid.
> Therefore, if the packet contains CRC data, pkt_len should contain the CRC data length.
> However, almost of drivers supported KEEP CRC feature didn't add the CRC data length to pkt_len.
> This patch adds description for KEEP CRC offload.
