Yes. He did. I have read it many a time, along with its companion ip-tunnels.tex. However iproute has two main commands: ip and tc. ip-cref.tex and ip-tunnels.txt only cover ip. I have no problem with either of them, other than perhaps him not providing them in the form of a man page.
But ip is a relatively simple command compared to tc, and all he provided for it was README.iproute2+tc. I guess without it, I would not have known the purpose of the tc command. For the rest I had to read the source.

Bugger future messes these people might create, how about fixing the ones they have left behind? I wrote my own doco when I decided to use tc in anger: http://www.stuart.id.au/russell/files/tc/doc so I am not asking for someone to do something I haven't done myself. And before you ask the obvious question: after dealing with the kernel devs once, I think Conroy must be easier to deal with. Perhaps I exaggerate, but only by a tiny bit.
