Considering that you also have the option of setting ds->assisted_learning_on_cpu_port = true and this will have less false positives, what are the reasons why you did not choose that approach?You're right. Hardware learning on CPU port does have some limitations. I have been testing a multi CPU ports patch, and assisted learning has to be used, because FDB entries should be installed like multicast ones, which point to all CPU ports.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? _______________________________________________ Linux-mediatek mailing list Linux-mediatek@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-mediatek
