Maybe I'm not seeing the bigger picture but it seems pretty orthogonal
to me.  Does using OFED 1.3 preclude using a qla4xxx host adapter?  IOW,
is there anything inherent in using OFED 1.3 as the networking fabric on
a (say) storage server that uses a QLogic ISP4XXX adapter to access it's
storage?

Yeah, the old conundrum.

Well, given the alternative that it's completely unbuildable in the
kernel when you choose OFED's iscsi options, is including the qla4xxx in
the OFED distribution, even untested so bad?

~sigh~  Yeah.

I wonder how many (if any) of our userbase we are going to upset if we
cease providing the qla4xxx driver in our kernels.  On the other hand, I
wonder how many we'd upset by not providing iSER and the newer
open-iscsi modules.
