I'm trying to run tdc, but keep getting following error even on clean
branch without my patches:

Vlad, not sure if you saw my email:
Apply Roman's patch and try again

cheers,

With patch applied I get following error:

Test 7d50: Add skbmod action to set destination mac
exit: 255 0

You may actually have broken something with your patches in this case.

Results is for net-next without my patches.

Do you have skbmod compiled in kernel or as a module?

Thanks, already figured out that default config has some actions
disabled.
Have more errors now. Everything related to ife:
