Don't really know about 1.

2. - there is a requeue function in the queues in net/sched and a 
comment in sch_api.c -

---requeue

    requeues once dequeued packet. It is used for non-standard or
    just buggy devices, which can defer output even if dev->tbusy=0.

I guess that gives a bit of hope.

Andy.
