[PATCH v6 00/34] e1000x cleanups (preliminary for IGB)

[Akihiko Odaki]

We are adding a new device named igb, yet another Intel NIC. As the new
implementation derives from e1000e, overhaul e1000e implementation first.
e1000 has many commonalities with e1000e so we also apply the corresponding
changes to the device if possible.

This was spun off from:
https://patchew.org/QEMU/20230112095743.20123-1-akihiko.odaki@daynix.com/

The changes from the series are as follows:
- Fixed code alignment in e1000.c. (Philippe Mathieu-Daudé)
- "e1000: Configure ResettableClass" and e1000e's corresponding patch was based
  on the old version so they are now updated. (Philippe Mathieu-Daudé)
- Added "e1000e: Remove extra pointer indirection"

The series was composed on patches submitted earlier for e1000e. The below
