Subject: [RFC] NET: Multiple queue hardware support

This patchset is an updated version of previous multiqueue network device
support patches.  The general approach of introducing a new API for multiqueue
network devices to register with the stack has remained.  The changes include
adding a round-robin qdisc, heavily based on sch_prio, which will allow
queueing to hardware with no OS-enforced queuing policy.  sch_prio still has
the multiqueue code in it, but has a Kconfig option to compile it out of the
qdisc.  This allows people with hardware containing scheduling policies to
use sch_rr (round-robin), and others without scheduling policies in hardware
to continue using sch_prio if they wish to have some notion of scheduling
priority.

The patches to iproute2 for tc will be sent separately, to support sch_rr.

I'm soliciting feedback for a 2.6.23 submission.  Thanks.
