Subject: [PATCH net-next 0/3] ipip/ip6tnl: allow to switch netns during encap/decap


This patch is a follow up of the previous serie witch add this functionality
for sit tunnels.

The goal is to add x-netns support for the module ipip and ip6_tunnel, ie the
encapsulation addresses and the network device are not owned by the same
namespace.

Note that the first patch is a fix of the previous serie.

Example to configure an ipip tunnel:

modprobe ipip
ip netns add netns1
ip link add ipip1 type ipip remote 10.16.0.121 local 10.16.0.249
ip l s ipip1 netns netns1
ip netns exec netns1 ip l s lo up
ip netns exec netns1 ip l s ipip1 up
ip netns exec netns1 ip a a dev ipip1 192.168.2.123 remote 192.168.2.121

or an ip6_tunnel:

modprobe ip6_tunnel
ip netns add netns1
ip link add ip6tnl1 type ip6tnl remote 2001:660:3008:c1c3::121 local 2001:660:3008:c1c3::123
ip l s ip6tnl1 netns netns1
ip netns exec netns1 ip l s lo up
ip netns exec netns1 ip l s ip6tnl1 up
ip netns exec netns1 ip a a dev ip6tnl1 192.168.1.123 remote 192.168.1.121
ip netns exec netns1 ip -6 a a dev ip6tnl1 2001:1235::123 remote 2001:1235::121
