84 - Mode 1 (VLAN-unaware): a port is in this mode when it is used as a standalone
87   bridge with ``vlan_filtering=1``. Access to the entire VLAN range is given to
93   bridge with ``vlan_filtering=1``, and the devlink property of its parent

237 SJA1105 switch 1 consumes 1 retagging entry for each VLAN on each user port
238 towards the CPU. It also consumes 1 retagging entry for each non-pvid VLAN that
242 In this case, SJA1105 switch 1 consumes a total of 11 retagging entries, as
245 - 8 retagging entries for VLANs 1 and 100 installed on its user ports
249   interested in it. The VLAN 1 is a pvid on SJA1105 switch 2 and does not need
257   switch 1 (``sw1p0`` - ``sw1p3``).

305 If br0 has vlan_filtering 1, then a new br1 interface needs to be created that
317 specified in IEEE 802.1Q-2018 (formerly 802.1Qbv). This means it can be used to
335 on egress. Using ``vlan_filtering=1``, the behavior is the other way around:
