GSO needs inner headers and inner protocol set properly to work. skb->inner_mac_header: skb_reset_inner_headers() assigns the current mac header value to inner_mac_header; but it is not set at the point, so we need to call skb_reset_inner_mac_header, otherwise gre_gso_segment fails: it does int tnl_hlen = skb_inner_mac_header(skb) - skb_transport_header(skb); ... if (unlikely(!pskb_may_pull(skb, tnl_hlen))) ... skb->inner_protocol should also be correctly set.
