Well the concerns we have do not apply to just iWARP, but RDMA/IP in general so this isn't really another technology. In fact, it seems that we now have IP-specific knowledge living in drivers/infiniband/core/cma.c which is suboptimal. > Unified wire iSCSI adapters have the same issue as iWARP wrt to managing > IP addresses and ports. If by Unified wire iSCSI you mean something that presents a SCSI interface together with an Ethernet interface where the two share the same MAC and IP address, then we have the same concerns with it as we do with iWARP or TOE.
