Of course preserving a flow consistency is must-be here, but I think
there are rehashing algorithms used in similar cases (sch_sfq) which
take care for this. As a matter of fact, I've thought of requeuing as
a best place to detect possible problems, but now I see that
Alexander's proposal let's to do this simply by observing this
TCQ_F_STOPPED flag [...]

Hmm... or maybe it doesn't? Since this is qdisc flag we don't know at
the top which tx_queue is a problem at the bottom...
