Two details worth noting: this only happens with a conduit MAC that strips
the non-standard 0x810X TPID into metadata while preserving the port bits,
which was not demonstrated here, and the same OUT_BAD outcome already
applies to other VLAN-metadata DSA taggers such as the tag_8021q family,
where proto becomes ETH_P_XDSA and also has no case in the switch. Should
the receive path here rely only on the in-band tag, or is degraded hashing
on the conduit acceptable for this configuration?
This is just getting too fringe. What about we merge this and look into this
when we have a user who actually want to do these things on this
old chip?
I don't think this is a blocker.
