It is now - briefly, at least - part of my job to look at backporting
agr(4) to 2.0.x.

Is there a document somewhere summarizing the kernel-internal interface
changes between 2.0 and 3.0, so I can go through and compare that to
what the various agr files use?  Or, alternatively, has anyone already
tried this (and is willing to share the experience)?  Or am I entirely
on my own for this?

I'm actually considering just rewriting it, since if I've understood
the end desire right, I don't want LACP, and that seems to be a major
contributor to the complexity of agr.
