4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Haishuang Yan <yanhaishuang@xxxxxxxxxxxxxxxxxxxx>
[ Upstream commit 5e263f712691615fb802f06c98d7638c378f5d11 ]
When NET_SWITCHDEV=n, switchdev_port_attr_set will return -EOPNOTSUPP,
we should ignore this error code and continue to set the ageing time.
Fixes: c62987bbd8a1 ("bridge: push bridge setting ageing_time down to switchdev")
