Queueing it in the driver is bad because it is no different than queueing it at the upper layer, which is what will happen when you return TX_BUSY. Because we've ripped out the qdisc requeueing logic (which is horribly complex and only existed because of TX_BUSY), it means that higher priority packets cannot preempt a packet that is queued in this way.
