There is some on Mellanox's website:

http://www.mellanox.com/related-docs/prod_software/Mellanox_EN_for_Linux_User_Manual_v2_0-3_0_0.pdf

But it it took weeks for $VENDOR to figure out what was
going on and why performance was so bad. It wasn't until
they got Mellanox into the calls that Mellanox pointed
this out to them.

cheers,
Chris
