Subject: [openib] add an enum for future RDS support
Message-id: 1221598570.1927.507.camel@firewall.xsintricity.com
O-Subject: [Patch RHEL5.3] Add an enum from OFED
Bugzilla: 462551
RH-Acked-by: Pete Zaitcev <zaitcev@redhat.com>

There has been some talk of possibly trying to enable the RDS protocol
(currently part of the OFED stuff, but I exclude it since it hasn't gone
to Linus' kernel yet) sometime prior to rhel5.4.  I've looked over all
the patches necessary to enable support *for* RDS without actually
putting RDS into our kernel.  There is only one and I'm attaching it
here.

There currently is no bugzilla for this, it has grown out of a request
from Oracle.  In particular, Oracle is planning to make RDS a
requirement in the future for RAC cluster configurations and
certifications.  However, RDS still isn't ready for inclusion IMO due to
the fact that it hasn't been submitted to Linus' kernel yet and because
there is talk about changing it from a net protocol that works over
TCP/IP or IB to just an IB ULP.  So, we didn't want to put it in 5.3,
but waiting until 5.4 will leave us uncertified for a long time.

All sorts of higher up management types have been in on these talks and
since this is *SO* minor (and already in OFED 1.4, so no danger of
allocating an enum that conflicts with upstream later), it was deemed
best to get this into 5.3 if for no other reason than to keep our
options open on how/when to support RDS in the future.
