These are needed to get the IPv6 Tunnel Encapsulation Limit option (RFC 2473) actually sent in packets. As a side effect, FoU and GUE IPv6 tunnels wouldn't work anymore unless you include... > Which then seems to be further fixed in > commit d4d576f5ab7edcb757bb33e6a5600666a0b1232d > "ip6_tunnel: Fix encapsulation layout" this one. But, for those tunnels to work, commit 84dad55951b0 ("udp6: fix encap return code for resubmitting") is also needed. I think making sure all those four commits are there would be the safest option. -- Stefano
