Currently, this test program uses invalid array for threshold level information.
What do you mean exactly here as "threshold level"? This term is fairly unclear to me and I don't remember of it being defined properly although you seem to have started using in some comments.
thanks,
Takashi
This commit replaces the array with valid information, which consists of newly exported TLV macros from kernel land.
