+.SH "DESCRIPTION"
+.SS rdma system set - set RDMA subsystem network namespace mode or
+privileged qkey mode
+
+.SS rdma system show - display RDMA subsystem network namespace mode and
+privileged qkey state
+
+.PP
+.I "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.
+.PP
+.I "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.
+
+.SH "EXAMPLES"
+.PP
+rdma system show
+.RS 4
+Shows the state of RDMA subsystem network namespace mode on the system and
+the state of privileged qkey parameter.
+.RE
+.PP
+rdma system set netns exclusive
+.RS 4
+Sets the RDMA subsystem in network namespace exclusive mode. In this mode RDMA devices
+are visible only in single network namespace.
+.RE
+.PP
+rdma system set netns shared
+.RS 4
+Sets the RDMA subsystem in network namespace shared mode. In this mode RDMA devices
+are shared among network namespaces.
+.RE
+.PP
+.PP
+rdma system set privileged-qkey on
+.RS 4
+Sets the privileged-qkey parameter to on. In this state non-privileged user
+is allowed to specify a controlled QKEY.
+.RE
+.PP
+rdma system set privileged-qkey off
+.RS 4
+Sets the privileged-qkey parameter to off. In this state non-privileged user
+is *not* allowed to specify a controlled QKEY.
