Subject: Re: [PATCH] net: dsa: mv88e6xxx: avoid error message on remove
 from VLAN 0

From: Nikita Yushchenko <>
Date: Fri, 31 May 2019 10:35:14 +0300

> When non-bridged, non-vlan'ed mv88e6xxx port is moving down, error
> message is logged:
> failed to kill vid 0081/0 for device eth_cu_1000_4
> This is caused by call from __vlan_vid_del() with vin set to zero, over
> call chain this results into _mv88e6xxx_port_vlan_del() called with
> vid=0, and mv88e6xxx_vtu_get() called from there returns -EINVAL.
> On symmetric path moving port up, call goes through
> mv88e6xxx_port_vlan_prepare() that calls mv88e6xxx_port_check_hw_vlan()
> that returns -EOPNOTSUPP for zero vid.
> This patch changes mv88e6xxx_vtu_get() to also return -EOPNOTSUPP for
> zero vid, then this error code is explicitly cleared in
> dsa_slave_vlan_rx_kill_vid() and error message is no longer logged.
