Bug description:
[Bug Description]
When a GRO packet is received by driver, the cwr field in the
struct tcphdr needs to be checked to decide whether to set the
SKB_GSO_TCP_ECN for skb_shinfo(skb)->gso_type.
[Steps to Reproduce]
1.load PF driver
2.turn off GRO of stack, turn on HW GRO
[Actual Results]

[Expected Results]
GRO run ok
[Reproducibility]
Inevitably
[Additional information]
Hardware: D06
Firmware: NA
Kernel: NA
[Resolution]
Adds hns3_gro_complete to do that, and adds the
hns3_handle_bdinfo to handle the hns3_gro_complete and
hns3_rx_checksum.
net: hns3: add hns3_gro_complete for HW GRO process
net: hns3: minor refactor for hns3_rx_checksum
