I was looking at the code if we can simply instead do:

[ "$TST_IPVER" == 6 ] && tst_net_require_ipv6

in the test library, but it looks like the parameters are parsed in the
tst_test.sh in the tst_run() function. Which means that the TST_IPVER is
not actually set until the test starts and the library has no way of
knowing the variable value beforehand.

I guess that we can actually move the option parsing code in the
tst_test.sh so that it happens just right after the script is sourced,
which would make things much easier as the TST_IPVER would end up being
defined in the tst_network.sh and we coud simply use the statement above
without any further hacks like this patch adds.

As a side effect we could clean up the test option parsing code since we
do actually have two different getopts loop in the tst_test.sh library
and as far as I can tell we can do just with one.
