I think in the upstream kernel look at commit f9bbe4477c30ece44296437ee26142b42ef8070b "net: dsa: Optional VLAN-based port separation for switches without tagging" by Vladimir Oltean. I intuitively think this is what we want to do in the end is use DSA_TAG_PROTO_8021Q but admittedly I don't think I understand VLANs well enough for enabling this. For OpenWrt using kernel v4.19 I have no idea what the best would be. I don't think Vladimir's work can be easily backported. I suppose some special hack to just bring up the DSA with a custom script is the best compromise for the time being. FYI this board supported by OpenWrt also has this switch: https://openwrt.org/toh/evaluation.boards/pb44 with a custom driver: https://github.com/openwrt/openwrt/blob/master/target/linux/ar71xx/files/drivers/spi/spi-vsc7385.c It's a MIPS device though, and I don't know if anyone is actively maintaining it and could test to migrate it to this new driver and help out?
