For offload with bnx2i and cxgb3i, this is going to be needed. Instead 
of the net ioctls, we have to pass this info down to the iscsi offload 
drivers using the iscsi interface.

For software iscsi with ibft, I think it will be useful too. I am just 
not sure if it might mess up other distro stuff. Have you evaluated 
them? Let's see if Hannes from SUSE or Hans from Red Hat have an opinion.
