+.RS 4
+Set type of specified devlink port to Ethernet.
+.RE
+.PP
+devlink port split pci/0000:01:00.0/1 count 4
+.RS 4
+Split the specified devlink port into four ports.
+.RE
+.PP
+devlink port unsplit pci/0000:01:00.0/1
+.RS 4
+Unplit the specified previously split devlink port.

+.RE
+.PP
+devlink port add pci/0000:06:00.0 flavour pcisf pfnum 0 sfnum 88
+.RS 4
+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 attribute and activate the function. Once function usage is completed,
+inactivate 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 inactive state and function's operational state is detached.
+.RE
+.PP
+devlink port del pci/0000:06:00.0/1
+.RS 4
+Delete previously created devlink port. It is recommended to first deactivate
+the function if the function supports state management.
+.RE
+.PP
+devlink port function set pci/0000:01:00.0/1 hw_addr 00:00:00:11:22:33
+.RS 4
+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.
+.RE
+.PP
+devlink port function set pci/0000:01:00.0/1 state active
+.RS 4
+Activate the function. This will initiate the function enumeration and driver loading.
+.RE
+.PP
+devlink port function set pci/0000:01:00.0/1 state inactive
+.RS 4
+Deactivate the function. This will initiate the function teardown which results
+in driver unload and device removal.
+.RE
+.PP
+devlink port function set pci/0000:01:00.0/1 hw_addr 00:00:00:11:22:33 state active
+.RS 4
+Configure hardware address and also active the function. When a function is
+activated together with other configuration in a single command, all the
+configuration is applied first before changing the state to active.
+.RE
+.PP
+devlink dev param show
+.RS 4
+Shows (dumps) all the port parameters across all the devices registered in the devlink.
+.RE
+.PP
+devlink dev param set pci/0000:01:00.0/1 name internal_error_reset value true cmode runtime
+.RS 4
+Sets the parameter internal_error_reset of specified devlink port (#1) to true.
+.RE
+.PP
+devlink port add pci/0000:06:00.0 flavour pcisf pfnum 0 sfnum 88 controller 1
+.RS 4
+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
