One example which immediately springs to mind is the RTL8139C+ which
Bill Paul has been playing with this very week.

Also, my Efficient Networks Lanai based ATM adapter has support of
kinds for this (albeit in ATM-land), even the fxp has Intel's proprietary
Priority Packet software for it (pardon the pun).

With the increased interest in VoIP and similar these days, perhaps hardware
DS/QoS support of this nature is something the project should explore?

I have heard the 'provision your network correctly' argument against this,
but this doesn't address the problem of pushing isochronous traffic through
a narrow pipe used to connect a branch office, so I find it unhelpful.
