* The hardware does not have distinct settings for interrupt
* moderation while the previous IRQ is being handled, so we should
* not use the 'irq' fields. However, an earlier developer
* misunderstood the meaning of the 'irq' fields and the driver did
* not support the standard fields. To avoid invalidating existing
* user documentation, we report and accept changes through either the
* standard or 'irq' fields. If both are changed at the same time, we
* prefer the standard field.
