From ec1d8ccb07deaf30fd0508af6755364ac47dc08d Mon Sep 17 00:00:00 2001 From: Hangbin Liu Date: Fri, 30 Mar 2018 09:44:00 +0800 Subject: vlan: also check phy_driver ts_info for vlan's real device 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.") Acked-by: Richard Cochran Signed-off-by: Hangbin Liu Signed-off-by: David S.
