You may want to disable interrupt moderation and manually configure
interrupt rate per queue if you have high pps. I have had a lot of
headaches with ix driver and fixed it by manually setting interrupt
rates.
sysctl hw.ix.enable_aim=0

What's strange about it? The interrupt rate only changes if traffic

core the queue is bound to, then the interrupt rate won't change.
Or are you confused about the units? I know ixl(4) uses usecs instead
of
Hz, so ix(4) should probably change to use that at some point.
By default `hw.ix.max_interrupt_rate: 31250` and I confused about some
queue exceed this.
And I can set dev.ix.0.queue4.interrupt_rate to 31250 (by sysctl) and
this changes accepted.
I am to be out of it.

Last -stable, no tuning. Is this normal?
