Hello Crisselle, 

    it's my fault not make myself clear，please allow me re-describe the problem。 

    i'm new to DPDK and network device program。 

    is it possible we are mirror traffic from switch/router to PF, then a program based on DPDK read packet from a VF related to the PF, presume we are mirror the traffic from PF to the VF （promiscuous），while the PF device still managed by the kernel driver(if it's possible), or managed by UIO driver.  at least, restart the DPDK based program will not influence the PF device state.
