Sorry for the slow response Ivan.

214, 7 and 1 are correct. But as far as I can see in my tables the QDSS
clock doesn't have any status (129 seems to be EBI1_CH0_RANGE).

The status_id was originally included because I was reading it and I saw
that Srinivas has some code that reads it, but unless it shows to be
useful we should probably just drop that entire column...

But for now please mark it as -1 or so and we can have a chat with
Srinivas on dropping the column later.
