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

[Narayan Desai]

We've had good luck using the iSER support in newer mainline and ubuntu
kernel (3.2+). I'd be somewhat surprised if that code hadn't been
backported by redhat, but we don't run it so I haven't paid much attention
to which patches they carry.
