From 3a1a793af5e713fb4920cf48194d0c23568297a7 Mon Sep 17 00:00:00 2001 From: "Russell King (Oracle)" Date: Thu, 28 Oct 2021 15:55:34 +0100 Subject: [PATCH] net: phylink: avoid mvneta warning when setting pause parameters mvneta does not support asymetric pause modes, and it flags this by the lack of AsymPause in the supported field. When setting pause modes, we check that pause->rx_pause == pause->tx_pause, but only when pause autoneg is enabled. When pause autoneg is disabled, we still allow pause->rx_pause != pause->tx_pause, which is incorrect when the MAC does not support asymetric pause, and causes mvneta to issue a warning. Fix this by removing the test for pause->autoneg, so we always check that pause->rx_pause == pause->tx_pause for network devices that do not support AsymPause.
