Currently, we get icmp6hdr via function icmp6_hdr(), which needs the skb transport header to be set first. But there is no rule to ask driver set transport header before netif_receive_skb() and bond_handle_frame(). So we will not able to get correct icmp6hdr on some drivers.

Fix this by using skb_header_pointer to get the IPv6 and ICMPV6 headers.
