Hi, all,
DPDK has introduced one offload: DEV_RX_OFFLOAD_KEEP_CRC. It means that
the device has the ablility of keeping CRC（four bytes at the end of
packet）of packet in RX.
In common scenarios, When one packet enter into NIC device, NIC
will check the CRC and then strip the CRC，at last send the packet into
the buffer.
So my question is:
why the DEV_RX_OFFLOAD_KEEP_CRC is introduced into DPDK? I think that
when the packet enter into the NIC, the CRC will has no significance to
APP. Or is there any scenarios that CRC is useful for APP？
Thanks for your reply.
