lwt: Add support to redirect dst.input
This patch adds the capability to redirect dst input in the same way that dst output is redirected by LWT. Also, save the original dst.input and and dst.out when setting up lwtunnel redirection. These can be called by the client as a pass- through. Signed-off-by: Tom Herbert <tom@herbertland.com> Signed-off-by: David S. Miller <davem@davemloft.net>
