             BUS_NAME/BUS_ADDRESS/PORT_INDEX


       type { eth | ib | auto }
              set port type

              eth - Ethernet

              ib - Infiniband

              auto - autoselect


   devlink port split - split devlink port into more
       DEV/PORT_INDEX - specifies the devlink port to operate on.


       count COUNT
              number of ports to split to.


   devlink port unsplit - unsplit previously split devlink port
       Could be performed on any split port of the same split group.


       DEV/PORT_INDEX - specifies the devlink port to operate on.


   devlink port show - display devlink port attributes
       DEV/PORT_INDEX - specifies the devlink port to show.  If this argument is omitted all ports
       are listed.


   devlink port health - devlink health reporting and recovery
       Is an alias for devlink-health(8).


   devlink port add - add a devlink port
       DEV - specifies the devlink device to operate on. or


       DEV/PORT_INDEX - specifies the devlink port index to use for the requested new port.  This is
       optional. When omitted, driver allocates unique port index.


       flavour { pcipf | pcisf }
              set port flavour

              pcipf - PCI PF port

              pcisf - PCI SF port


       pfnum PFNUMBER
              Specifies PCI pfnumber to use on which a SF device to create


       sfnum SFNUMBER
              Specifies sfnumber to assign to the device of the SF.  This field is optional for
              those devices which supports auto assignment of the SF number.


       controller CNUM
              Specifies controller number for which the SF port is created.  This field is optional.
              It is used only when SF port is created for the external controller.


   devlink port function set - Set the port function attribute(s).
       DEV/PORT_INDEX - specifies the devlink port to operate on.


       hw_addr ADDR
              Hardware address of the function to set. This is a Ethernet MAC address when port type
              is Ethernet.


       state { active | inactive }
              New state of the function to change to.

              active - Once configuration of the function is done, activate the function.

              inactive - To inactivate the function and its device(s), set to inactive.


   devlink port del - delete a devlink port
       DEV/PORT_INDEX - specifies the devlink port to delete.


   devlink port param set - set new value to devlink port configuration parameter
       DEV/PORT_INDEX - specifies the devlink port to operate on.


       name PARAMETER
              Specify parameter name to set.


       value VALUE
              New value to set.


       cmode { runtime | driverinit | permanent }
              Configuration mode in which the new value is set.

              runtime - Set new value while driver is running. This configuration mode doesn't re‐
              quire any reset to apply the new value.

              driverinit - Set new value which will be applied during driver initialization. This
              configuration mode requires restart driver by devlink reload command to apply the new
              value.

              permanent - New value is written to device's non-volatile memory. This configuration
              mode requires hard reset to apply the new value.


   devlink port param show - display devlink port supported configuration parameters attributes
       DEV/PORT_INDEX - specifies the devlink port to operate on.

       name PARAMETER Specify parameter name to show.  If this argument, as well as port index, are
       omitted - all parameters supported by devlink device ports are listed.


   devlink port function rate - manage devlink rate objects
       Is an alias for devlink-rate(8).


EXAMPLES
       devlink port show
           Shows the state of all devlink ports on the system.

       devlink port show pci/0000:01:00.0/1
           Shows the state of specified devlink port.

       devlink port set pci/0000:01:00.0/1 type eth
           Set type of specified devlink port to Ethernet.

       devlink port split pci/0000:01:00.0/1 count 4
           Split the specified devlink port into four ports.

       devlink port unsplit pci/0000:01:00.0/1
           Unplit the specified previously split devlink port.

       devlink port health show
           Shows status and configuration of all supported reporters registered on all devlink
           ports.

       devlink port health show pci/0000:01:00.0/1 reporter tx
           Shows status and configuration of tx reporter registered on pci/0000:01:00.0/1 devlink
           port.

       devlink port add pci/0000:06:00.0 flavour pcisf pfnum 0 sfnum 88
           Add a devlink port of flavour PCI SF on PCI PF having number 0 with SF number 88.  To
           make use of the function an example sequence is to add a port, configure the function at‐
           tribute and activate the function. Once function usage is completed, inactivate the func‐
           tion and finally delete the port. When there is desire to reuse the port without dele‐
           tion, it can be reconfigured and activated again when function is in inactive state and
           function's operational state is detached.

       devlink port del pci/0000:06:00.0/1
           Delete previously created devlink port. It is recommended to first deactivate the func‐
           tion if the function supports state management.

       devlink port function set pci/0000:01:00.0/1 hw_addr 00:00:00:11:22:33
           Configure hardware address of the PCI function represented by devlink port.  If the port
           supports change in function state, hardware address must be configured before activating
           the function.

       devlink port function set pci/0000:01:00.0/1 state active
           Activate the function. This will initiate the function enumeration and driver loading.

       devlink port function set pci/0000:01:00.0/1 state inactive
           Deactivate the function. This will initiate the function teardown which results in driver
           unload and device removal.

       devlink port function set pci/0000:01:00.0/1 hw_addr 00:00:00:11:22:33 state active
           Configure hardware address and also active the function. When a function is activated to‐
           gether with other configuration in a single command, all the configuration is applied
           first before changing the state to active.

       devlink dev param show
           Shows (dumps) all the port parameters across all the devices registered in the devlink.

       devlink dev param set pci/0000:01:00.0/1 name internal_error_reset value true cmode runtime
           Sets the parameter internal_error_reset of specified devlink port (#1) to true.

       devlink port add pci/0000:06:00.0 flavour pcisf pfnum 0 sfnum 88 controller 1
           Add a devlink port of flavour PCI SF on controller 1 which has PCI PF of number 0 with SF
           number 88. To make use of the function an example sequence is to add a port, configure
           the function attribute and activate the function. Once the function usage is completed,
           deactivate the function and finally delete the port. When there is desire to reuse the
           port without deletion, it can be reconfigured and activated again when function is in in‐
           active state and function's operational state is detached.
