Based on this analysis and the fact that with your re-work the interrupts
seems to be naturally spread across the CPUs, will it be safe to revert
Jesse's patch

e2e64a932 genirq: Set initial affinity in irq_set_affinity_hint()

as it overwrites the previously set IRQ affinity mask for some of the
devices?

That's a good question. My gut feeling says yes.

Jesse do you want to send the revert for the patch?

Also, I think it was you who suggested cc'ing
intel-wired-lan ml as that allows intel folks, to do some initial
testing?
If so, we can do that here (IMHO).

Patch sent here:
https://lore.kernel.org/lkml/20210501021832.743094-1-jesse.brandeburg@intel.com/T/#u (local)

Any testing appreciated!
