8   When a port is initially created, it is empty (has no phys).  All
9   ports must have at least one phy to operated, and all wide ports
10   must have at least two.  The current code makes no difference
11   between ports and wide ports, but the only object that can be
12   connected to a remote device is a port, so ports must be formed on
13   all devices with phys if they're connected to anything.
