Thanks for your review, sorry I forget to add here from ptach 6 Devlink documentation
+  $ devlink dev param set pci/0000:bdf name fastboot value 1 cmode driverinit
+
+The devlink param fastboot is set to true via devlink param command, by
+passing name ``fastboot``, value ``1`` and cmode ``driverinit``.
+
+::
+
+  $ devlink dev reload pci/0000:$bdf action driver_reinit
+
+The wwan device is put into fastboot mode via devlink reload command, by
+passing ``driver_reinit`` action.

I will add here.
