     NAME
          devlink - Devlink tool

     SYNOPSIS
          devlink [ OPTIONS ] { dev|port help }

          devlink [ -force ] -batch filename

     OPTIONS
          -V, --Version
               Print the version of the devlink utility and exit.

          -b, -batch <FILENAME>
               Read commands from provided file or standard input and
               invoke them.  First failure will cause termination of
               devlink.

          -force
               Don't terminate devlink on errors in batch mode.  If
               there were any errors during execution of the commands,
               the application return code will be non zero.

          -n, --no-nice-names
               Turn off printing out nice names, for example netdevice
               ifnames instead of devlink port identification.

          -j, --json
               Generate JSON output.

          -p, --pretty
               When combined with -j generate a pretty JSON output.

          -v, --verbose
               Turn on verbose output.

          -s, --statistics
               Output statistics.

          -N, -Netns <NETNSNAME>

          dev  - devlink device.

          port - devlink port.

          monitor
               - watch for netlink messages.

          sb   - devlink shared buffer configuration.

          resource
               - devlink device resource configuration.

          region
               - devlink address region access

          health
               - devlink reporting and recovery

          trap - devlink trap configuration

          COMMAND

          Specifies the action to perform on the object.  The set of
          possible actions depends on the object type.  As a rule, it
          is possible to show (or list ) objects, but some objects do
          not allow all of these operations or have some additional
          commands. The help command is available for all objects. It
          prints out a list of available commands and argument syntax
          conventions.

          If no command is given, some default command is assumed.

          Usually it is list or, if the objects of this class cannot
          be listed, help.

     EXIT STATUS
          Exit status is 0 if command was successful or a positive
          integer upon failure.
