MIXEDLAYER_RESTRAT = True + BULKMIXEDLAYER = False.

The following is in OM4_025 MOM_parameter_doc.all

BULKMIXEDLAYER = False ! [Boolean] default = True

MIXEDLAYER_RESTRAT = True ! [Boolean] default = False ! If true, a density-gradient dependent re-stratifying ! flow is imposed in the mixed layer. ! This is only used if BULKMIXEDLAYER is true.

So are we using MIXEDLAYER_RESTRAT, even though BULKMIXEDLAYER = False?

If we are in fact using MIXEDLAYER_RESTRAT, then the comment in the code should be corrected. It is very confusing.
