Hi Dean. This looks good to me, though I agree Luca's point about
show_port_info_all() is compelling. We are enforcing the paired topology
today but may not always.

I don't view it as something which should block the testsuite, but this is
worth tracking. Can you make a Bugzilla ticket for this, and add to the
minutes for the DTS meeting (either tomorrow or 2 weeks)?
