Yes, it's there, but almost impossible to hit: first of all, iSCSI HBAs never listen on a port, so that can never collide. Second, iSCSI HBAs only establish connections to iSCSI targets on the iSCSI port -- so really your only chance of a problem is if you ran an offloaded and non-offloaded iSCSI initiator on the same IP to the same target, _and_ you got unlucky on the local ports that you chose. So in practice no one will hit this. -- Roland Dreier || For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/index.html -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
