This global kinda bothers me - anything we can do about removing it?
We obviously didn't have it now - just one (even bigger limit!) per
queue, so that's 4000 frames default per interface ... now you're down
to 512 for the entire hardware. Perhaps keeping it per interface at
least gets away the worst of the contention here?
