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.

I will try to do this.  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.
