* 0 = This was a scheduled retune. Timestamp fields should be
* ignored.
*
* flags[1]: 1 = Operation completed successfully.
* 0 = Operation failed.
*
* For "Tune NOW" requests, a failure may occur as the result
* of the tuning algorithm failing to occur, and such other
* unexpected failurs.
*
* The scheduled tune request will failure if the retune queue
* is full.

* flags[7:2] Reserved. Set to 0.
