Subject: net: Convert ip6_tnl_net_ops
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=66997ba0834ac1b3f22873d349614405e48c69d7;p=openwrt%2Fstaging%2Fblogic.git

net: Convert ip6_tnl_net_ops

These pernet_operations are similar to ip6gre_net_ops. Exit method
unregisters all net ip6_tnl tunnels, and it looks like another
pernet_operations are not interested in foreign net tunnels list.
So, it's possible to mark them async.
