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:

Please make sure you have these in your kernel config:

CONFIG_NET_ACT_IFE=y
CONFIG_NET_IFE_SKBMARK=m
CONFIG_NET_IFE_SKBPRIO=m
CONFIG_NET_IFE_SKBTCINDEX=m

For tdc to run all the tests, it is assumed that all the supported tc
actions/filters are enabled and compiled.
hello,

looking at ife.json, it seems that we have at least 4 typos in
'teardown'. 

It does

$TC actions flush action skbedit

in place of 

$TC actions flush action ife

On my fedora28 (with fedora28 kernel), fixing them made test 7682 return
'ok' (and all others in ife category, except ee94, 7ee0 and 0a7d).

regards,
I can confirm that on net-next kernel version that I use, there are also
multiple teardowns of actions type skbedit after actually creating ife
action in file ife.json. However, tests pass when I enabled config
options that Roman suggested:

ok 119 - 7682 # Create valid ife encode action with mark and pass control
