				3368	* for partial matches exists with a few limitations. First, hardware only

				3370	* Second, hardware is limited to using one mask for a flow type and cannot
				3371	* use a separate mask for each filter.
				3372	*
				3373	* To support these limitations, if we already have a configured filter for
				3374	* the specified type, this function enforces that new filters of the type
				3375	* match the configured input set. Otherwise, if we do not have a filter of
				3376	* the specified type, we allow the input set to be updated to match the
				3377	* desired filter.
				3378	*
				3379	* To help ensure that administrators understand why filters weren't displayed
				3380	* as supported, we print a diagnostic message displaying how the input set
				3381	* would change and warning to delete the preexisting filters if required.
				3382	*
