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:
https://patchwork.kernel.org/project/netdevbpf/patch/20210308135509.3040286-1-olteanv@gmail.com/

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
