From: Leon Romanovsky <leonro@xxxxxxxxxxxx> >From Parav, When there are multiple rdma devices exist in a system, it is desired to have per net namespace based devices without any compatibility devices. Therefore, add a query and set option through which user can disable/enable default mode of sharing a rdma device in multiple net namespaces. In subsequent series, a new netlink command will be added to change the namespace of an rdma device.
