From 7cbbee050c959f41b512599bafd99685f419ce26 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Fri, 8 Mar 2019 01:21:27 +0100 Subject: net: dsa: mv88e6xxx: Set correct interface mode for CPU/DSA ports By default, the switch driver is expected to configure CPU and DSA ports to their maximum speed. For the 6341 and 6390 families, the ports interface mode has to be configured as well. The 6390X range support 10G ports using XAUI, while the 6341 and 6390 supports 2500BaseX, as their maximum speed.
