From 75dad2520fc37345075498e9c5aa1355b4993dbc Mon Sep 17 00:00:00 2001 From: Benedikt Spranger Date: Fri, 28 Jun 2019 18:58:11 +0200 Subject: [PATCH] net: dsa: b53: Disable all ports on setup A b53 device may configured through an external EEPROM like the switch device on the Lamobo R1 router board. The configuration of a port may therefore differ from the reset configuration of the switch. The switch configuration reported by the DSA subsystem is different until the port is configured by DSA i.e. a port can be active, while the DSA subsystem reports the port is inactive. Disable all ports and not only the unused ones to put all ports into a well defined state. Signed-off-by: Benedikt Spranger Reviewed-by: Florian Fainelli Signed-off-by: David S.
