This is a note to let you know that I've just added the patch titled net: phylink: avoid mvneta warning when setting pause parameters to the 5.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: net-phylink-avoid-mvneta-warning-when-setting-pause-.patch and it can be found in the queue-5.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit be251510d3bc5a8f72773062baf868ee99afc908 Author: Russell King (Oracle) <rmk+kernel@xxxxxxxxxxxxxxx> Date: Thu Oct 28 15:55:34 2021 +0100 net: phylink: avoid mvneta warning when setting pause parameters [ Upstream commit fd8d9731bcdfb22d28e45bce789bcb211c868c78 ] 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.
