You may wish to propose a new command structure that covers both IRQ and DMA moderation. They seem to be related, since DMA cannot be delayed longer than the corresponding IRQ. We are currently lacking a way to specify different IRQ moderation for multiqueue devices where the queues are not all used in the same way.

Confirming you are suggesting a replacement or an alternate for the current -c/-C coalesce settings with perhaps some room reserved for some future coalescing type features and enable settings per queue?
[...] Yes. I'm not insisting that you must do this instead of just defining the operations for DMA coalescing, but it would be helpful.
