net: phy: don't clear BMCR in genphy_soft_reset 2019-03-26T00:08:21+00:00 Heiner Kallweit hkallweit1@gmail.com 2019-03-22T19:00:20+00:00 d29f5aa0bc0c321e1b9e4658a2a7e08e885da52a So far we effectively clear the BMCR register. Some PHY's can deal with this (e.g. because they reset BMCR to a default as part of a soft-reset) whilst on others this causes issues because e.g. the autoneg bit is cleared. Marvell is an example, see also thread [0]. So let's be a little bit more gentle and leave all bits we're not interested in as-is. This change is needed for PHY drivers to properly deal with the original patch.
