From: "Steven Rostedt (Red Hat)" The backport of upstream commit 205983c43700ac3 ("sit: allow to use rtnl ops on fb tunnel") had a dependency on commit 5e6700b3bf98 ("sit: add support of x-netns"). The dependency was on the way that commit unregistered the sit devices. Since the entire commit 5e6700b3bf98 is not necessary for a backport we only need to backport the part required for the backport of 205983c43700ac3. This is the loop to unregister the sit devices where dev->rtnl_link_ops == &sit_link_ops.
