Changes since v1:

https://lore.kernel.org/qemu-devel/20250115150112.346497-1-npiggin@gmail.com/

- Made changes as suggested by Odaki san in v1. Renamed some
  functions and changed some comments, added a Fixes: tag.
- Bug fix in "net/e1000e|igb: Fix interrupt throttling logic"
  patch to notify only causes that were not masked.
- Squashed patch 8 into patch 2 and improved changelog and comments,
  retained the 7813 interrupts/sec limit for e1000e mitigation.
- Reordered patches in the series.
- Improved the changelog for "net/e1000e|igb: Fix interrupt throttling
  logic" to be clearer about the problems and fixes.
- In that patch, made the delayed irq timer rearming path a bit clearer.
- Reduced test iterations to avoid increasing qtest time too much
  for e1000e interrupt throttling test.

Thanks,
Nick
