This patch does not apply:
> + ipv6h = ipv6_hdr(skb);
> + ershdr = (struct erspan_base_hdr *)skb->data;
> ver = (ntohs(ershdr->ver_vlan) & VER_MASK) >> VER_OFFSET;
> tpi->key = cpu_to_be32(ntohs(ershdr->session_id) & ID_MASK);
> pkt_md = (struct erspan_metadata *)(ershdr + 1);
There is not "pkt_md = ..." assignment in net-next on this line.
