[ Upstream commit df8ed346d4a806a6eef2db5924285e839604b3f9 ]
Currently also the pause flags are removed from phydev->supported because they're not included in PHY_DEFAULT_FEATURES. I don't think this is intended, especially when considering that this function can be called via phy_set_max_speed() anywhere in a driver. Change the masking to mask out only the values we're going to change. In addition remove the misleading comment, job of this small function is just to adjust the supported and advertised speeds.
