13 .. list-table:: Driver-specific parameters implemented
20 * - ``best_effort_vlan_filtering``
23 - Allow plain ETH_P_8021Q headers to be used as DSA tags.
27 - Can terminate untagged traffic over switch net
28 devices even when enslaved to a bridge with
30 - Can terminate VLAN-tagged traffic over switch net
31 devices even when enslaved to a bridge with
32 vlan_filtering=1, with some constraints (no more than
33 7 non-pvid VLANs per user port).
34 - Can do QoS based on VLAN PCP and VLAN membership
35 admission control for autonomously forwarded frames
36 (regardless of whether they can be terminated on the
41 - User cannot use VLANs in range 1024-3071. If the
42 switch receives frames with such VIDs, it will
43 misinterpret them as DSA tags.
44 - Switch uses Shared VLAN Learning (FDB lookup uses
46 - When VLANs span cross-chip topologies, the total
47 number of permitted VLANs may be less than 7 per
48 port, due to a maximum number of 32 VLAN retagging
