Nice work, LGTM, few small notes (could be fixed before merge).
Reviewed-by: Petr Vorel <pvorel@suse.cz>
Out of curiosity, did you test this on Two Host Configuration [2] (i.e. ssh)?
Or just netns?

Anything from testcases/network/stress/ns-tools/ is deprecated,
including check_icmpv{4,6}_connectivity. But this can be safely removed.
Although I don't see any connectivity check in tst_net.sh, it should be handled
there. IMHO it's needed at least for for two host based configuration, but it does not harm to test also netns based setup, thus somewhere after init_ltp_netspace.

I guess you removed -s (security), to get more descriptive error.
But then you IMHO need to use tst_brk to quit the test.
Or if it was deliberate to keep other tests running, then test1
would print TPASS "Test finished successfully" even it fails due this.

nit: I'd be consistent with previous (1s vs. 1).
The rest LGTM.
