     31     - u32
     32     - runtime
     33     - Sets an interval for periodic ACL region rehashes. The value is
     34       specified in milliseconds, with a minimum of ``3000``. The value of
     35       ``0`` disables periodic work entirely. The first rehash will be run
     36       immediately after the value is set.
     37
     38The ``mlxsw`` driver supports reloading via ``DEVLINK_CMD_RELOAD``
