Subject: net: phylink: avoid mvneta warning when setting pause parameters
Patch-mainline: v5.16-rc1
Git-commit: fd8d9731bcdfb22d28e45bce789bcb211c868c78
References: bsc#1119113 FATE#326472

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.
