No description provided.

An RDMA device can only be assigned to a network namespace when the RDMA
subsystem is set to an "exclusive" network namespace mode. When the subsystem is
set to "shared" mode, an attempt to assign an RDMA device to a network namespace
will result in failure. Additionally, "If there are active network namespaces
and if one or more RDMA devices exist, changing mode from shared to exclusive
returns error code EBUSY."
