The function netif_skb_features() will disable the TSO feature by using dflt_features_check() if the driver does not implement ndo_features_check ops, which may cause performance degradation problem when hns3 hardware can do multiple tagged TSO. Also, the HNS3 hardware only supports checksum on the SKB with a max header len of 480 bytes, so remove the checksum and TSO related features when the header len is over 480 bytes.
