/** enum ipa_status_mask - IPA status mask field bitmask hardware values */
Define the remaining values for opcode and exception fields in the IPA packet status structure. Most of these values are powers-of-2, suggesting they are meant to be used as bitmasks, but that is not the case. Add comments to be clear about this, and express the values in decimal format.
