ipv4: redirect dst output to lwtunnel output
For input routes with tunnel encap state this patch redirects dst output functions to lwtunnel_output which later resolves to the corresponding lwtunnel output function. This has been tested to work with mpls ip tunnels. Signed-off-by: Roopa Prabhu <roopa@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
