net: Fix userland breakage wrt. linux/if_tunnel.h
Reported by Andrew Walrond <andrew@walrond.org> Changeset c19e654ddbe3831252f61e76a74d661e1a755530 ("gre: Add netlink interface") added an include of linux/ip.h to linux/if_tunnel.h We can't really let that get exposed to userspace because this conflicts with types defined in netinet/ip.h which userland is almost certainly going to have included either explicitly or implicitly. So guard this include with a __KERNEL__ ifdef. Signed-off-by: David S. Miller <davem@davemloft.net>
