This mitigates the problem that the extra pseudo-interfaces enlarge the interface list and confuse the user. The hw.usb.no_pf knob has been removed. Instead of using IFF_CANTCONFIG, the usbusN interfaces reject any ioctls for interface configuration intentionally. Also, set ifp->if_afdata[AF_INET6] to NULL to eliminate INET6-specific handling such as ND6 options. Reviewed by: hselasky END
