On second thought:
Dawid noticed that SFQ and RED appear immune to this problem
(i think any non classful qdisc would exhibit same behavior).
Maybe we should allow for this behavior for consistency.
The suggestion that Alexey made  of setting limit of 1 to default 
child fifo when tx_queue_len is 0 is the better appraoch instead of
touching these devices.

cheers,
jamal
