yes, this is true with all the testcases in this file.  In general
this test file needs some catching up with the latest test infra.
eg check_err is  not consistent with the rest of the newer tests. Plus
we should move all the tests in this file to use netns.
I am thinking of keeping this as is to be consistent with the rest of
the testcases in this file and address this in a future upgrade to all
tests.
