Subject: net: Specify the owning module for lwtunnel ops
From: Robert Shearman <rshearma@xxxxxxxxxxx>
[ Upstream commit 88ff7334f25909802140e690c0e16433e485b0a0 ]
Modules implementing lwtunnel ops should not be allowed to unload
while there is state alive using those ops, so specify the owning
module for all lwtunnel ops.
