Which does beg the question why I hadn’t considered the admission control issue when originally implementing against the software bridge. That’s my bad, and perhaps had I discovered tc-flower earlier I would have a different mental model of how to map this to mv88e6xxx.

Also whilst the admission control is necessary to correctly implement 802.1Qat and pass the Avnu test suites, it might not matter for many networks.

I will think about how to implement these semantics with tc-flower/TCAM, likely after I take a look at submitting your DSA in-band/Marvell RMU patches.
