I don=E2=80=99t 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=E2=80=99ve 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.=
