Can't we just keep these at the top along with the rest of the
variables? I do not see them redefined anywhere but maybe I miss
something.

	    This is no longer set in the tst_test.sh.

And we do not return from the tst_test.sh when -h was passed so I guess
that we can just delete this part of the check.

Here as well, it does not seem that these variables are redefined so can
we move the . dhcp_lib.sh just before the tst_run?

Here as well, are these actually changed if we set them before we source
the tst_net.sh?

>  tst_run

Other than these minor things this is rather nice cleanup that
simplifies the code a bit.

I guess that in the long term we can clean the shell tests so that there
is no need to have explicit call to the tst_run and instead the test
would be started automatically from the sourced tst_test.sh

Anyways I think that this patchset is good to go as long as we shuffle
the stuff that can be shuffled. With that:
