Hi,
I want to use 'rte_kni_alloc()' to create a kernel iface and
use it to test application rx. From the api and example in
'examples/kni/main.c', i saw the 'conf' argument is assigned
with pci info of a dpdk port.
Want to ask if this is compulsory... Must kni always be
used together with a dpdk port?
Thanks,

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.
