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

[Shachar Raindel <raindel@mellanox.com>]

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.
