[Lustre-discuss] Luster 1.8.3 Qlogic OFED 1.4.2

[Kevin Van Maren]

If you replace OFED, you do not need to rebuild the kernel (unless you 
want to patch/change it), so you can install the binary Lustre kernel.  
You do need to rebuild Lustre (or at least the kernel modules) (step 
#3), as o2ib must be built against the OFED you are running.
