565 * moderation is explicitly changed then TX IRQ moderation is

568 *
569 * The hardware does not support a limit on the number of completions
570 * before an IRQ, so we do not use the max_frames fields. We should
571 * report and require that max_frames == (usecs != 0), but this would
572 * invalidate existing user documentation.
573 *
574 * The hardware does not have distinct settings for interrupt
575 * moderation while the previous IRQ is being handled, so we should
576 * not use the 'irq' fields. However, an earlier developer
577 * misunderstood the meaning of the 'irq' fields and the driver did
578 * not support the standard fields. To avoid invalidating existing
579 * user documentation, we report and accept changes through either the
580 * standard or 'irq' fields. If both are changed at the same time, we
581 * prefer the standard field.
582 *
583 * We implement adaptive IRQ moderation, but use a different algorithm
584 * from that assumed in the definition of struct ethtool_coalesce.
