No, I don't think it is compulsory--I am using it in this way.  You can
modify the example program to remove the references to the physical PCI
device and have the KNI instance created as a standalone device.

Alternatively, you can use something like librte_pmd_ring, a ring-based
poll-mode driver, to associate KNI with a purely software-based PMD.  In
this case, you are associating KNI with a DPDK port, but no physical
Ethernet device.
