Sounds nice, I'm interested in giving this a try on the LS1028A ENETC.

Do you have any more tooling around tperf? Does the talker advertise
the stream in such a way that a switch could reserve bandwidth too?

Do you plan to add this to the kernel tree (e.g.
tools/testing/selftests/tsn or such) or how do you want to maintain
this long-term?

I've added more people from NXP who may also be interested.
