Data to be transferred. There are two supported ways data may be conveyed, corresponding to the
two members of the DataTransfer union:
1) vmo_transfer: A region within a VMO previously known to the driver. This VMO must have been
established via `PacketStreamControl.RegisterVmos` (if client-allocated) or
`PacketStreamControl.AllocateVmos` (if driver-allocated). Future requests refer to this
buffer by the unique `vmo_id`. Because VMOs are reused across requests, the one-time
cost of pinning/mapping is amortized.
2) data: The payload is provided directly within the message. This mode is intended for
small transfers or control information, not high-throughput streaming.
