From: Vladimir Oltean <vladimir.oltean@nxp.com>
This is a proposal for an alternative solution to the problems presented
by Tobias here:
https://patchwork.kernel.org/project/netdevbpf/cover/20210308150405.3694678-1-tobias@waldekranz.com/
The key difference is that his patch series makes dsa_slave_vlan_rx_add_vid
accept -EOPNOTSUPP and silently transforms it into an error code of 0,
while my patch series avoids calling dsa_slave_vlan_rx_add_vid when it
is not needed.
Note that the series applies on top of this other bugfix:

Vladimir Oltean (4):
net: dsa: on 'bridge vlan add', check for 8021q uppers of all bridge
ports
net: dsa: prevent hardware forwarding between unbridged 8021q uppers
net: dsa: don't advertise 'rx-vlan-filter' if VLAN filtering not
global
net: dsa: let drivers state that they need VLAN filtering while
standalone
