The HFI ("Host Fabric Interface") network interface is the internal cluster
fabric of IBM's PERCS supercomputer. The hardware design is under US export
control, so we cannot release hardware specs. There is a writeup of
publically available information about the system available here:
http://sourceforge.net/projects/hfidevicedriver/files/docs/hfi_general_desc_v2.1.txt
hfi_core contains the resource management to set up communications paths for
network traffic. Calls are provided for kernel drivers, and also for setting
up direct user-space access to HFI windows.
hf_if contains the kernel network driver.
The driver has been running in the lab for several months. The full patch is
around 22000 lines, so we've split out a minimal device/network driver that
can send and receive through the simplest path. Once that much gets reviewed
we'll start adding on to it.
Patches are against net-2.6 (Is that the correct tree for us to use?).

net-next-2.6 would be the correct tree at the moment. net-2.6 is
currently destined for 2.6.38 and it is too late to add a driver to
that.
