net: hns3: Add skb chain when num of RX buf exceeds MAX_SKB_FRAGS
MAX_SKB_FRAGS in protocol stack is defined as: MAX_SKB_FRAGS is 17 when PAGE_SIZE is 4K. If HW enable GRO, it may merge small packets and the rx buffer may be more than MAX_SKB_FRAGS. So driver will add skb chain when RX buffer num. more than MAX_SKB_FRAGS. Signed-off-by: Peng Li <lipeng321@huawei.com> Signed-off-by: Salil Mehta <salil.mehta@huawei.com> Signed-off-by: David S.
