Hi,

Sorry for my slow reply, here is the patch (for 4.4). I have to admit that I don't remember all the details and I can't find my notes, but the purpose of the change is to ensure that the code at the top of mt7530_apply_config() is run once on boot. This seemed to be required to isolate the ports properly during boot, before the correct vlan configuration is applied.

This fix is not perfect, in the sense that I still sometimes see a few packages leaking if the bootloader is not updated. As I wrote earlier, I tried to replicate all configuration steps from the Mediatek driver, as wel as compare with the one in LEDE, but was not sucessful.
