-sja1105 devlink support
-=======================
-
-This document describes the devlink features implemented
-by the ``sja1105`` device driver.
-
-Parameters

-
-.. list-table:: Driver-specific parameters implemented
- :widths: 5 5 5 85

- - Description
- * - ``best_effort_vlan_filtering``
- - Boolean
- - runtime
- - Allow plain ETH_P_8021Q headers to be used as DSA tags.
-
- Benefits:
-
- - Can terminate untagged traffic over switch net
- devices even when enslaved to a bridge with
- vlan_filtering=1.
- - Can terminate VLAN-tagged traffic over switch net
- devices even when enslaved to a bridge with
- vlan_filtering=1, with some constraints (no more than
- 7 non-pvid VLANs per user port).
- - Can do QoS based on VLAN PCP and VLAN membership
- admission control for autonomously forwarded frames
- (regardless of whether they can be terminated on the
- CPU or not).
-
- Drawbacks:
-
- - User cannot use VLANs in range 1024-3071. If the
- switch receives frames with such VIDs, it will
- misinterpret them as DSA tags.
- - Switch uses Shared VLAN Learning (FDB lookup uses
- only DMAC as key).
- - When VLANs span cross-chip topologies, the total
- number of permitted VLANs may be less than 7 per
- port, due to a maximum number of 32 VLAN retagging
- rules per switch.
