From 6d004d6cc73920299adf4cfe25010b348fc94395 Mon Sep 17 00:00:00 2001 From: Steffen Klassert Date: Mon, 12 May 2014 09:09:26 +0200 Subject: vti: Use the tunnel mark for lookup in the error handlers. We need to use the mark we get from the tunnels o_key to lookup the right vti state in the error handlers. This patch ensures that. Fixes: df3893c1 ("vti: Update the ipv4 side to use it's own receive hook.") Fixes: fa9ad96d ("vti6: Update the ipv6 side to use its own receive hook.")
