From 5684abf7020dfc5f0b6ba1d68eda3663871fce52 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Mon, 17 Jun 2019 21:34:13 +0800 Subject: ip_tunnel: allow not to count pkts on tstats by setting skb's dev to NULL iptunnel_xmit() works as a common function, also used by a udp tunnel which doesn't have to have a tunnel device, like how TIPC works with udp media. In these cases, we should allow not to count pkts on dev's tstats, so that udp tunnel can work with no tunnel device safely. Signed-off-by: Xin Long Signed-off-by: David S.
