Subject: vlan: also check phy_driver ts_info for vlan's real device
From: Hangbin Liu <liuhangbin@xxxxxxxxx>
[ Upstream commit ec1d8ccb07deaf30fd0508af6755364ac47dc08d ]
Just like function ethtool_get_ts_info(), we should also consider the
phy_driver ts_info call back. For example, driver dp83640.
Fixes: 37dd9255b2f6 ("vlan: Pass ethtool get_ts_info queries to real device.")
