[PKTGEN]: Fix multiqueue oops.
Initially pkt_dev can be NULL this causes netif_subqueue_stopped to oops. The patch below should cure it. But maybe the pktgen TX logic should be reworked to better support the new multiqueue support. Signed-off-by: Robert Olsson <robert.olsson@its.uu.se> Signed-off-by: David S.
