Ohh, great, thank you! I kept forgetting this :)

That looks pretty good, but perhaps add

CONFIG_MACSEC=y

to support those tests, and

CONFIG_FTRACE=y

to make the trace-cmd stuff work? I think, actually not 100% sure what's
needed to make that work ...

Thanks!

I started down the path of adding macsec support, but gave up after a
while. Will give it another go.

Yes it would be helpful to have that working by default.

I'm attaching the kernel .config that I'm using and that has support for
all the test cases.

That's included in the attached version as well.

 Install the required tools: at least 'kvm', if you want tracing trace-cmd,
 valgrind if you want, etc.
