IIUC, we could have main() do something like:
for env [NetDrvContEnv, NetDrvEpEnv]:
with env as cfg:
[...]
ksft_run(tests, args=(cfg,))
And then the tests could call helpers that check cfg.netns to use the
nk_{guest,host}_ip6 addresses when true, otherwise use the regular
addresses?
It should be doable if I'm following your drift.
