Log:
Assigning the unit number for each interfaces could not use ubus-parent
because it could differ depending on the host controller type. It could
lead the duplicate unit number assignment.

I think you will get a multiple unit number if you unload+load a driver like
EHCI/OHCI/UHCI. I suggest that you only make one ifp instance and route all
traffic through that one.
