From: Elena Ufimtseva <elena.ufimtseva@xxxxxxxxxx> For sbdf'si parsing in rmrr command line add __parse_pci with addtional parameter def_seg. __parse_pci will help to identify if segment was found in string being parsed or default segment was used. Make a wrapper parse_pci so the rest of the callers are not affected.
