Hi Petr,
three times... does it happen after these patches?
It's sourced by the helper to export the environment variables and export
the variables that are not yet set, so once here.
And each of the tests sources it once as well...

This helper is really optional, I'm not quite follow you here, what
is the purpose of moving it's setup to tst_net_run()? The tests run
fine without the helper, and with runltp as well.
For netns and runltp, each test-case flushes interfaces and waits for
completion of DAD process, I think we could remove this latency by:
* checking that interface already has the needed configuration, no need
to flush and re-add anything, check that there is no xfrm policy, etc.
* may be save temp configuration in a file on the first test-case run and
source it for the next test-cases
* pass nodad when setting IPv6 addresses
Thanks,
Alexey
