+From 6ccf21ca77ec092aa63b3daff66dc9f0d0e1be93 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] datapath: compat: Fix build on RHEL 7.3
+
+RHEL 7.3 provides upstream tunnel but it does not support name_assign_type
+attribute in net-device. This patch fixes the build problem by backporting
+functions with name_assign_type, and using proper flags in acinclude.m4 to
+invoke backport functions.
+
+Tested on RHEL 7.3 with kernel 3.10.0-514.el7.x86_64
