RDMA/core: Add a netlink command to change net namespace of rdma device
Provide an option to change the net namespace of a rdma device through a netlink command. When multiple rdma devices exists in a system, and when containers are used, this will limit rdma device visibility to a specified net namespace. An example command to change net namespace of mlx5_1 device to the previously created net namespace 'foo' is: $ ip netns add foo $ rdma dev set mlx5_1 netns foo Signed-off-by: Parav Pandit <parav@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
