The HFI network interface is the internal cluster fabric of IBM's PERCS
supercomputer. The device driver patch for 2.6.36, hfi-utils, and an
introduction to the hardware are available on the sourceforge page
(http://sourceforge.net/projects/hfidevicedriver). The hardware design
is under US export control, so we cannot release hardware specs.
The HFI device driver allows direct user-space access to network
resources; a reference library will be uploaded to
http://sourceforge.net/projects/halreferencelib in the next few days.
The driver has been running in the lab for several months. The
user-space access is essentially complete. We are still working on IPv6,
and we are now starting work on an ofed-over-hfi driver, but we'd like
to start the review process without them.

Nobody is going to look at your code, let alone help review it
for inclusion, if you just say "go look at this stuff on this
sourceforge web site."
You have to post the kernel patches here, one by one.

Sorry, thought I was following the instructions for large patches in
Documentation/SubmittingPatches. It is currently one patch of about
22000 lines, around 630k.
Most of the patch is new files, I'm figuring one file per email.
There are 2 files just under 3000 lines, 4 in the 1000-1700 line range,
and some smaller ones. Do I need to break any of those up further?
