From 8b318f30ab4ef9bbc1241e6f8c1db366dbd347f2 Mon Sep 17 00:00:00 2001 From: Antoine Tenart Date: Fri, 1 Mar 2019 11:52:08 +0100 Subject: net: mvpp2: fix validate for PPv2.1 The Phylink validate function is the Marvell PPv2 driver makes a check on the GoP id. This is valid an has to be done when using PPv2.2 engines but makes no sense when using PPv2.1. The check done when using an RGMII interface makes sure the GoP id is not 0, but this breaks PPv2.1. Fixes it. Fixes: 0fb628f0f250 ("net: mvpp2: fix phylink handling of invalid PHY modes") Signed-off-by: Antoine Tenart Signed-off-by: David S.
