Subject: [PATCH v1 10/10] IB/ucm: Add partial support for network namespaces

It is impossible to completely support network namespaces for UCM, as
we cannot identify the target IPoIB device. However, we add support
which will work if the user is following the IB-Spec Annex 11 (RDMA IP
CM Services) with the service ID and private data formatting.
