[PATCH v2 net 0/3] Clear rx-vlan-filter feature in DSA when necessary

From: Vladimir Oltean <vladimir.oltean@nxp.com>

Patches 2 and 3 address the problems raised by Tobias here:
https://patchwork.kernel.org/project/netdevbpf/cover/20210308150405.3694678-1-tobias@waldekranz.com/

The key difference compared to Tobias' patch is that his approach 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.

Patch 1 is another issue I found while working on a solution.

Vladimir Oltean (3):
  net: dsa: only unset VLAN filtering when last port leaves last
    VLAN-aware bridge
  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
