I don’t believe local traffic is an issue (if it were, I imagine one could use cgroups to control which processes could send frames of a particular priority). (Kieran, feel free to correct me.)

What I’ve done in the current patch (behind a Kconfig option) is to assume that static FDB/MDB entries on MQPRIO ports are for AVB alone. But this may be incompatible with IGMP snooping, if that also results in the creation of static MDB entires.

Adding MQPRIO/CBS support without this admission control is definitely an option and perhaps a good first step, the proviso being that when bridging, SRP would not provide a guaranteed bandwidth reservation.
