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.
