+Subject: [PATCH] net: phy: fix waiting for link
+
+phydev->adjust_link() is called only from phy_update_status() when the
+link status changes during that function. phydev->link is also updated
+in genphy_update_link() called from phy_wait_aneg_done(), so it can
+happen that phydev->link changes outside of phy_update_status(), thus
+phydev->adjust_link is never called and no link change notice is
+printed.
+
+Instead of calling genphy_update_link() from phy_wait_aneg_done(), call
+phy_update_status(). This makes sure that a link change is properly
+noticed.
+
+Fixes: 8f75aa496dcb ("net: reply to ping requests")
