From eccde89aa4764fd16b490e96e5dbbdb51cb0051b Mon Sep 17 00:00:00 2001 From: Mathias Kresin Date: Mon, 2 Jul 2018 22:09:04 +0200 Subject: [PATCH] kernel: fix AT8032 PHY phy id mask Don't mask bit 4 of the AT8022 phy id. If bit 4 of the AT8022 phy id (0x004dd023) is masked, it will match the phy id of the AR8327 switch (0x004dd033) as well. It results in applied at803x driver settings/callbacks, which will at least limit the AR8327 phys to 100MBit operation instead of the possible 1000MBit.
