Moving this device means moving all tunnels backed by this device
rather than specific tunnel device. Thats why it does not look right
to move such device.

I agree it seems weird in general. There were two things that made me wonder:
 * It doesn't appear that VXLAN or GRE do this.
 * The use case for moving a single tunnel to a different namespace is
to have the device and socket live in different places. I guess
conceptually this could apply to collect_md devices as well. (Maybe to
have harder isolation between inside and outside the tunnel?)

I'm not really sure what the best answer is but at least we should be
consistent across tunnel types.

I agree with Jesse that consistent behaviour is desirable. If needed,
let's change it for all encap types.
