From 7cefb0b0e91191185ddd26912cc52d589218fa47 Mon Sep 17 00:00:00 2001 From: "Russell King (Oracle)" Date: Tue, 20 Jul 2021 12:15:26 +0100 Subject: net: phylink: cleanup ksettings_set We only need to fiddle about with the supported mask after we have validated the user's requested parameters. Simplify and streamline the code by moving the linkmode copy and update of the autoneg bit after validating the user's request. Signed-off-by: Russell King (Oracle) Signed-off-by: David S.
