From 2b6fd3ea438c742d162a40a124b0181922633163 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Wed, 25 Sep 2019 02:47:07 +0200 Subject: [PATCH] net: dsa: qca8k: Fix port enable for CPU port MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The CPU port does not have a PHY connected to it. So calling phy_support_asym_pause() results in an Opps. As with other DSA drivers, add a guard that the port is a user port.
