This write-only INTEGER object, when written, causes the switch to restore the HRE-X PseudoCAM's hash function to its factory default value and program that into the HRE-X hardware. An admin uses this to revert to the known-default hash behavior, for example after an optimization attempt made lookup performance worse or unpredictable. For example, an admin writes a value here to undo a prior xylanHrexHashOptimize call and return the PseudoCAM hash to its default state.
