From c1ea5d672aaff08da337dee735dbb548e3415585 Mon Sep 17 00:00:00 2001 From: Jiri Benc Date: Thu, 20 Aug 2015 13:56:23 +0200 Subject: ip_tunnels: add IPv6 addresses to ip_tunnel_key Add the IPv6 addresses as an union with IPv4 ones. When using IPv4, the newly introduced padding after the IPv4 addresses needs to be zeroed out. Signed-off-by: Jiri Benc Acked-by: Thomas Graf Acked-by: Alexei Starovoitov Signed-off-by: David S.
