Because of the hardware constraints, hns3 network engine doesn't support
sending packets with more than eight fragments. And hns3 pmd driver
tries to reassemble these kind of packets to meet hardware requirements.
Currently, there are two problems:
1) when the input buffer_len * 8 < pkt_len, the packets are impossible
to be reassembled into 8 Buffer Descriptors. In this case, the
packets will be passed to hardware, which eventually causes a
hardware reset.
2) The meta data in origin packets which are required to fill into the
descriptor haven't been copied into the reassembled pkts.
This patch adds a check for 1) to ensure such packets will be dropped by
driver and copies useful meta data from the origin packets to the
reassembled packets.
