[PATCH v3 00/12] hw/e1000e|igb: interrupts and qtests fixes

[Nicholas Piggin <npiggin@gmail.com>]

Since v2:
https://lore.kernel.org/qemu-devel/20250411043128.201289-1-npiggin@gmail.com/

Mostly fixed comments from Akihiko Odaki

- e1000e change initial ITR as well as EITR
- Preserve EITR writable bits
- Use SCALE_US constant instead of 1000
- Fix register field definitions to not trample on code from Linux header
- Split the big fixes patch into several pieces

It is difficult to split the big fix into pieces because some of the
bugs are inter-dependent. I think I came up with a way to do it.

Thanks,
Nick
