From 239fb791d4ee194740e69fe9694f58ec404d1689 Mon Sep 17 00:00:00 2001 From: Thomas Graf Date: Tue, 5 May 2015 15:09:21 +0200 Subject: [PATCH] vxlan: Correctly set flow*i_mark and flow4i_proto in route lookups VXLAN must provide the skb mark and specifiy IPPROTO_UDP when doing the FIB lookup for the remote ip. Otherwise an invalid route might be returned. Signed-off-by: Thomas Graf Signed-off-by: David S.
