The if_max_devs table as in the past been an immutable default that controls the mapping of index => (bus,unit) for all boards and all HBAs for each interface type. Since adding this mapping information to the HBA device itself is currently unwieldly from the perspective of retrieving this information at option parsing time (e.g, within drive_new), we consider the alternative of marking the if_max_devs table mutable so that later configuration and initialization can adjust the mapping at will, but only up until a drive is added, at which point the mapping is finalized.
