gre: add collect_md mode to ERSPAN tunnel
Similar to gre, vxlan, geneve, ipip tunnels, allow ERSPAN tunnels to operate in 'collect metadata' mode. bpf_skb_[gs]et_tunnel_key() helpers can make use of it right away. OVS can use it as well in the future. Signed-off-by: William Tu <u9012063@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
