[Users] Issues installing iSER initiator on a Scientific Linux 6.4 (OFED 3.5-2) box

[Narayan Desai]

We were able to use the mainline kernel code. OFED started integrating
upstream in preparation for kernel release 3.2. While it isn't the newest
code, it has worked well enough for us. Things seem even better if you can
make it to 3.5 or 3.8.
