RTNETLINK answers: Invalid argument
Anything wrong with the command syntax?
I tried this example here, and it got accepted ok. I am using the
current net-next master. The first thing that comes to mind is that
perhaps you backported some old version of some of the patches (so it's
different than what's upstream now).
Was on master of kernel.org. Will try net-next master now.

Today I have tried with RT kernel and it looks great. I can see the
frames in the correct order. Here are the complete set of commands
used with RT kernel. Just used taprio, no ETF. I introduced a guard
band in between schedules. Not sure if that is needed. I will try
without it and see if the capture looks the same.
