Chad? If it cannot be removed easily, I will prepare the temporary documentation patch to mark the field as deprecated. On the topic of this original patch: I'll remove SCM_TSTAMP_HWSYS and will simplify ee_info to only hold a type. No need for an explicit index field if we simply assume that the ts[] index is always 0, except for SCM_TSTAMP_HW, which is 2. We can even copy that one into both fields 0 and 2 and consider the latter as a legacy workaround.
