sorry, the -roX and -sfX notations are mine; i'm backporting everything
to 2.4.20 for testing and most of the patches have to be tweaked one way
or another, so I gave them all my own names to help keep them straight.
-ro1 and -ro2 come from Robert's posts here, and -ro3 is what you get
when you apply

ftp://robur.slu.se/pub/Linux/net-development/skb_recycling/e1000_pci_2.pat

on top of that.

For what it's worth, I've subjected various e1000 chipsets to just about
every kind of synthetic load all the way up to the maximum theoretical
full-duplex gigE framerate for hours without a hiccup. I'm using
backports from 2.5 with the TSO stuff stripped out. Judging from my
apache logs and the emails I get, quite a few others have been using
those patches on 2.4 too, but I've received no real complaints.
