Subject: [PATCH] b=15316 i=cliffw i=wangyb

Build OFED 1.3's kernel-ib and kernel-ib-devel with our patched lustre
server kernel for RHEL 4 and 5 and SLES 10.  SLES 9 is not supported by
OFED 1.3.
Since OFED 1.3 provides a newer open-iscsi stack, prefer those modules
from the kernel-ib over those provided by the vendor kernels.
Additionally, build Lustre with o2iblnd support.
