Subject: [PATCH AUTOSEL for 4.14 045/100] ipvlan: Add the skb->mark as flow4's
 member to lookup route

From: Gao Feng <gfree.wind@....163.com>

[ Upstream commit a98a4ebc8c61d20f0150d6be66e0e65223a347af ]

Current codes don't use skb->mark to assign flowi4_mark, it would
make the policy route rule with fwmark doesn't work as expected.
