Subject: [PATCH net 0/4] net: dsa: b53: Various ARL fixes
Hi David, Andrew, Vivien, Jakub,
This patch series fixes a number of short comings in the existing b53
driver ARL management logic in particular:
- we were not looking up the {MAC,VID} tuples against their VID, despite
having VLANs enabled
- the MDB entries (multicast) would lose their validity as soon as a
single port in the vector would leave the entry
- the ARL was currently under utilized because we would always place new
entries in bin index #1, instead of using all possible bins available,
thus reducing the ARL effective size by 50% or 75% depending on the
switch generation
- it was possible to overwrite the ARL entries because no proper space
verification was done
This patch series addresses all of these issues.
