Trivial change, agreed on jabber.

The updated code uses interface index to match the interface detected by
the test with the interface found by the IfaceMgr. This is to avoid issues
on Linux whereby Netlink-based implementation doesn't return the virtual
interface names, but rather physical interface names.
