3.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nicolas Dichtel <nicolas.dichtel@xxxxxxxxx>
[ Upstream commit 205983c43700ac3a81e7625273a3fa83cd2759b5 ]
rtnl ops where introduced by ba3e3f50a0e5 ("sit: advertise tunnel param via
rtnl"), but I forget to assign rtnl ops to fb tunnels.
Now that it is done, we must remove the explicit call to
unregister_netdevice_queue(), because the fallback tunnel is added to the queue
in sit_destroy_tunnels() when checking rtnl_link_ops of all netdevices (this
is valid since commit 5e6700b3bf98 ("sit: add support of x-netns")).
