Subject: [PATCH 04/31] net: dsa: b53: Always use dev->vlan_enabled in b53_configure_vlan()

From: Florian Fainelli <[email-masked]>
Date: Thu, 6 Feb 2020 11:07:45 -0800

[ Upstream commit df373702bc0f8f2d83980ea441e71639fc1efcf8 ]

b53_configure_vlan() is called by the bcm_sf2 driver upon setup and
indirectly through resume as well. During the initial setup, we are
guaranteed that dev->vlan_enabled is false, so there is no change in
behavior, however during suspend, we may have enabled VLANs before, so we
do want to restore that setting.

Fixes: dad8d7c6452b ("net: dsa: b53: Properly account for VLAN filtering")
Fixes: 967dd82ffc52 ("net: dsa: b53: Add support for Broadcom RoboSwitch")
