From e85ec74ace29acfda4afdfd56df122a0a62e6a1a Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Tue, 19 Sep 2017 10:46:46 -0700 Subject: net: dsa: bcm_sf2: Defer port enabling to calling port_enable There is no need to configure the enabled ports once in bcm_sf2_sw_setup() and then a second time around when dsa_switch_ops::port_enable is called, just do it when port_enable is called which is better in terms of power consumption and correctness.
