From 4826d2c4fcbfcc3ba7887a197143ffe4d444a3d3 Mon Sep 17 00:00:00 2001 From: Antonio Borneo Date: Wed, 25 Nov 2020 00:07:56 +0100 Subject: [PATCH] net: phy: realtek: read actual speed on rtl8211f to detect downshift The rtl8211f supports downshift and before commit 5502b218e001 ("net: phy: use phy_resolve_aneg_linkmode in genphy_read_status") the read-back of register MII_CTRL1000 was used to detect the negotiated link speed. The code added in commit d445dff2df60 ("net: phy: realtek: read actual speed to detect downshift") is working fine also for this phy and it's trivial re-using it to restore the downshift detection on rtl8211f. Add the phy specific read_status() pointing to the existing function rtlgen_read_status().
