Hi Roland,

This patchset adds support for RDS as an Infiniband ULP. RDS is an
Oracle-originated protocol used to send IPC datagrams (up to 1MB) reliably,
and is used currently in Oracle RAC and Exadata products. It's lived
in OFED for 2+ years and I think it's time to get it upstream -- most
likely into your -next tree for .30, but if it snuck into .29 via the
"new code merge-window exception" then even better.

I've run checkpatch & sparse to clean up as many issues as possible so
what remains are really the design peculiarities (aka warts) that arise
from being a protocol designed by one company for a single critical
application. I think upstreaming this code is the first step towards
working out those issues, and making the end result available to a wider
audience.

Also available for review at:
git://git.openfabrics.org/~agrover/ofed_1_4/linux-2.6 for-roland

Thoughts? shortlog follows.

Thanks -- Regards -- Andy
