there are a lot of permutations to cover.

This feature needs to work with VRF from the beginning. v4, v6, with and
without VRF.

This patch can be folded into the previous one, and the drop the
only_tcp_authopt function. The script has always allowed a single test
to be run by name (-t arg), so '-t tcp_authopt' runs tcp_authopt which
covers v4 and v6 with and without vrf.
