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.
