after studying your proposal a bit, i can see where you were confused. but i can't help but think if you'd read ifconfig(8), as instructed, particularly looking at the output of "ifconfig <if> media", you'd have figured it out (i didn;t initially realise how this works either). your change will clarify that confusion, at least somewhat, i guess. but then it's putting information relevant to the full-duplex mediaopt in a less relevant place. which makes it less helpful for people who know how it works. and then the autoselect text will contain information about default mediaopts, but not mediatypes. i don;t think your idea will work will. but if you want us to look at it seriously, you'll need to provide a diff for man4 which addresses all this stuff for all the relevant drivers. my instinct is that you'll be wasting your time. jmc
