DESCRIPTION

     The entry points described here are invoked from a device
     driver's mc_propinfo(9E) entry point to associate information
     such as default values, permissions, or allowed value ranges.

     Each one of these functions takes as first argument the property
     information handle which is passed to the mc_propinfo(9E) as
     argument.

     mac_prop_info_set_perm() specifies the property of the
     property. The permission is passed through the perm argument, and
     can be set to one of the following values.

         MAC_PROP_PERM_READ	The property is read-only.

	 MAC_PROP_PERM_WRITE	The property is write-only.

	 MAC_PROP_PERM_RW	The property can be read and written.

     The driver is not required to call mac_prop_info_set_perm() for
     every property. If the driver does not call that function for a
     specific property, the framework will assume that the property
     has read and write permissions, corresponding to
     MAC_PROP_PERM_RW.

     mac_prop_info_set_default_uint8(),
     mac_prop_info_set_default_str(), and
     mac_prop_info_set_default_link_flowctrl() are used to associate
     a default value with a specific property.

     mac_prop_info_set_range_uint32() is used by a driver to associate
     an allowed range of values for a specific property. The range is
     defined by the min and max argument passed by the device driver.
