Hi Babu,

It is not clear how "event ID" and "other parameters" are relevant to this
change since (in this context) it is only RMID and CLOSID that can be
found in rdtgroup.

Could you please elaborate what you meant with: "These are passed individually,
resulting in architecture specific function calls."?
