You mean if the IB router is also an IP router for IPoIB?
Then I think there are some serious semantic problems to solve for the
RDMA CM -- because you are using an IP address to define a
destination, but since that address is on the other side of an IP
router, there's no way to know it even belongs to an IB port.
