The e2e_node topology_manager check have a early, quick check to rule out systems without sriov device, thus skipping the tests. The first version of the ckeck detected PFs, (Physical Functions), under the assumption that VFs (Virtual Functions) were already been created. This works because, obviously, you can't have VFs without PFs. However, it's a little safer and easier to understand if we check firectly for VFs, bailing out from systems which don't provide them. Nothing changes for properly configured test systems. Signed-off-by: Francesco Romani <fromani@redhat.com>
