    If usbnet is resumed by remote wakeup, generally there are
    some packets comming to be handled, so allocate and submit
    rx URBs in usbnet_resume to avoid delays introduced by tasklet.
    Otherwise, usbnet may have been runtime suspended before the
    usbnet_bh is executed to schedule Rx URBs.
    
    Without the patch, usbnet can't recieve any packets from peer
    in runtime suspend state if runtime PM is enabled and
    autosuspend_delay is set as zero.
