Ah, mt7530 is one of the switches which has multiple CPU ports, I had
forgotten that. In that case, then static FDB entries are pretty much
the only way to go indeed.

I forget which ones are the modes in which the multi-CPU feature on
mt7530 is supposed to be used: static assignment of user ports to CPU
ports, or LAG between the CPU ports, or a mix of both?

MT7530 only supports static assignment, by changing the port matrix.

MT7531 also supports hardware LAG, but I don't think it's ideal because
its CPU ports have different speeds (one 1Gbps RGMII and the other 2.5Gbps
HSGMII).
