> Hm shouldn't that timeout only hit if the driver is not providing NETDEV_EVENT_RX_COMPLETE / NETDEV_EVENT_TX_COMPLETE events? That's where _send_queued_pkt() is usually called, GNRC_NETIF_PKTQ_DEQUEUE_MSG appears more like a fall-back to me.
I see the point, but as it is now, drivers that provide RX_DONE and TX_DONE still try to schedule the msg. IMO the scheduling should then be done only if the driver cannot report the states back. Otherwise it will just add delay
