## DESCRIPTION
### rdma dev set - rename RDMA device or set network namespace or set RDMA device adaptive-moderation
### rdma dev show - display RDMA device attributes
       _DEV_ - specifies the RDMA device to show.  If this argument is omitted all devices are listed.


## EXAMPLES
       rdma dev
           Shows the state of all RDMA devices on the system.

       rdma dev show mlx5_3
           Shows the state of specified RDMA device.

       rdma dev set mlx5_3 name rdma_0
           Renames the mlx5_3 device to rdma_0.

       rdma dev set mlx5_3 netns foo
           Changes the network namespace of RDMA device to foo where foo is previously created using
           iproute2 ip command.

       rdma dev set mlx5_3 adaptive-moderation [on/off]
           Sets the state of adaptive interrupt moderation for the RDMA device.
           This is a global setting for the RDMA device but the value is printed for each CQ indi‐
           vidually because the state is constant from CQ allocation.
