- - "single", for contiguous buffer mode (high-order alloc);
- - "multi", for multiblock mode;
- - "ExI", for DCI handler mode;

- provided there are no active users and tracing is not enabled,
- otherwise the write will fail.

- Description: (RW) Configure MSC buffer size for "single" or "multi" modes.

- power of 2. In multiblock mode, this is a comma-separated list

- windows is not limited.
- Writing to this file deallocates existing buffer (provided
- there are no active users and tracing is not enabled) and then
- allocates a new one.
