Subject: [PATCH net] net: phylink: avoid mvneta warning when setting pause parameters
Date: Thu, 28 Oct 2021 15:55:34 +0100 [thread overview]
Message-ID: <E1mg6oY-0020Bg-Td@rmk-PC.armlinux.org.uk> (raw)
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.
