I'm afraid, that You have right.

I plan to make support for VLAN filtering for this switch. Maybe we can 
work together?

I see three possible solutions for port separation after VLAN support:

1. Use this only:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/networking/dsa/configuration.rst#n211
2. Use 8021q tag based solution.
3. Use tag_8021q tag based solution and try to use VLAN_KEEP_TAG_ENA for 
dual vlan tagging.
