====================
net: dsa: lantiq_gswip: clean up and improve VLAN handling
This series was developed by Vladimir Oltean to improve and clean up the
VLAN handling logic in the Lantiq GSWIP DSA driver.
As Vladimir currently doesn't have the availability to take care of the
submission process, we agreed that I would send the patches on his
behalf.
The series focuses on consolidating the VLAN management paths for both
VLAN-unaware and VLAN-aware bridges, simplifying internal logic, and
removing legacy or redundant code. It also fixes a number of subtle
inconsistencies regarding VLAN ID 0 handling, bridge FDB entries, and
brings the driver into shape to permit dynamic changes to the VLAN
filtering state.
Notable changes include:
- Support for bridge FDB entries on the CPU port
- Consolidation of gswip_vlan_add_unaware() and gswip_vlan_add_aware()
into a unified implementation
- Removal of legacy VLAN configuration options and redundant
assignments
- Improved handling of VLAN ID 0 and PVID behavior
- Better validation and error reporting in VLAN removal paths
- Support for dynamic VLAN filtering configuration changes
Overall, this refactor improves readability and maintainability of the
Lantiq GSWIP DSA driver. It also results in all local-termination.sh
tests now passing, and slightly improves the results of
bridge-vlan-{un,}aware.sh.
All patches have been authored by Vladimir Oltean; a small unintended
functional change in patch "net: dsa: lantiq_gswip: merge
gswip_vlan_add_unaware() and gswip_vlan_add_aware()" has been ironed out
and some of the commit descriptions were improved by me, apart from that
I'm only handling the submission and will help with follow-up
discussions or review feedback as needed.
Despite the fact that some changes here do actually fix things (in the
sense that selftests which would previously FAIL now PASS) we decided
that it would be the best for this series of patches to go via net-next.
If requested some of it can still be ported to stable kernels later on.
