* xge_hal_device_poll().
* Note that HAL does not maintain its own
* polling context. HAL relies on ULD to
* provide one.
* @queue_size_initial: Initial size of the HAL protected event queue.

* The queue is used to exchange and process slow-path
* events. See xge_hal_event_e.
* @queue_size_max: Maximum size of the HAL queue. Depending on the load,
* the queue may grow at run-time up to @queue_max_size.
* @tracebuf_size: Size of the trace buffer. Set it to '0' to disable.
* HAL configuration. (Note: do not confuse HAL layer with (possibly multiple)
* HAL devices.)
* Currently this structure contains just a few basic values.
* Note: Valid (min, max) range for each attribute is specified in the body of
