Description

rdmasystemset-setRDMAsubsystemnetworknamespacemodeor
       privileged qkey mode

   rdmasystemshow-displayRDMAsubsystemnetworknamespacemode,
       privileged qkey state and whether RDMA monitoring is supported.

       NEWMODE - specifies the RDMA subsystem mode. Either exclusive or shared.  When user wants to assign
       dedicated RDMA device to a particular network namespace, exclusive mode should be set before creating any
       network namespace. If there are active network namespaces and if one or more RDMA devices exist, changing
       mode from shared to exclusive returns error code EBUSY.

       When RDMA subsystem is in shared mode, RDMA device is accessible in all network namespace. When RDMA
       device isolation among multiple network namespaces is not needed, shared mode can be used.

       It is preferred to not change the subsystem mode when there is active RDMA traffic running, even though
       it is supported.

       NEWSTATE - Specifies the new state of the privileged-qkey parameter, either on or off.  This parameter
       determines whether a non-privileged user is allowed to specify a controlled QKEY or not.

Examples

       rdma system show
           Shows the state of RDMA subsystem network namespace mode on the system, the state of privileged qkey
           parameter and whether RDMA monitor is supported.

       rdma system set netns exclusive
           Sets the RDMA subsystem in network namespace exclusive mode. In this mode RDMA devices are visible
           only in single network namespace.

       rdma system set netns shared
           Sets the RDMA subsystem in network namespace shared mode. In this mode RDMA devices are shared among
           network namespaces.

       rdma system set privileged-qkey on
           Sets the privileged-qkey parameter to on. In this state non-privileged user is allowed to specify a
           controlled QKEY.

       rdma system set privileged-qkey off
           Sets the privileged-qkey parameter to off. In this state non-privileged user is *not* allowed to
           specify a controlled QKEY.
