Give the value and the "supported" bit names that reflect what they are. Show both the "supported" bit and the value as bitfields, because that's what they are. Show the "supported" bit before the value. Show the metric value as decimal; there's nothing particularly hexadecimal about it. The "supported" bit is 1 if it's *not* supported and 0 if it *is* supported. Fetch the byte for the metric within dissect_metric(), rather than in the call to dissect_metric().
