From cf18b7788fe1bf99e9c2ab580b065bf2d3cb1a34 Mon Sep 17 00:00:00 2001 From: Jérôme Pouiller Date: Thu, 3 Dec 2015 10:02:35 +0100 Subject: net: phy: reset only targeted phy It is possible to address another chip on same MDIO bus. The case is correctly handled for media advertising. It is taken into account only if mii_data->phy_id == phydev->addr. However, this condition was missing for reset case.
