From 2536862311d2276454ddef9dc36d6551a4b400fd Mon Sep 17 00:00:00 2001 From: Tom Herbert Date: Mon, 17 Aug 2015 13:42:24 -0700 Subject: 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 Signed-off-by: David S.
