What is the best approach for DSA_TAG_PROTO_NONE switches? DSA_TAG_PROTO_8021Q or just vlan filtering and configuration without tagging support? Both solutions can give You port separation. Personally I prefer simple vlan separation. This method was used in OpenWRT for many non-dsa switches. But it need to create API for dsa devices. > For OpenWrt using kernel v4.19 I have no idea what the best would > be.

Pb44 isn't ported to ath79 yet. I think, it is abandoned at this moment.
