From: Yishai Hadas <redacted> Set uid as part of RQ commands so that the firmware can manage the RQ object in a secured way. That will enable using an RQ that was created by verbs application to be used by the DEVX flow in case the uid is equal.

= {} is the preferred version of this, right?
{0} explicitly initializes the first element to zero and only works if
the first element happens to be something integral..
