But In short the FDB and VLAN part are very different. The FDB logic to dump entry add and remove is entirely different. And the mt7530 itself is full of unrelated function (specific to the first revision of the mt7530 switch) so I have to move lots of code around. If asked I can do it but I have to also introduce lots of extra change. > Also, let's try not to reach v20..
