Just found a nice forum post that keeps track of Intel's RST/RSTe drivers. I'm a bit sceptical since I can't find the latest version on Intel.com but thought I'd post the link here so I can go back later and have a look. It might be legit, it might not.

Links, commands and settings I someday probably won't find again
