From 607fca9acfb62a9caf7bd46771ecbc4d8fec7388 Mon Sep 17 00:00:00 2001 From: David Ahern Date: Wed, 24 Aug 2016 20:10:45 -0700 Subject: [PATCH] net: veth: Set features for MPLS veth does not really transmit packets only moves the skb from one netdev to another so gso and checksum is not really needed. Add the features to mpls_features to get the same benefit and performance with MPLS as without it. Reported-by: Lennert Buytenhek Signed-off-by: David Ahern Signed-off-by: David S.
