[PATCH 00/31] Introduce igb

[Akihiko Odaki]

igb is a family of Intel's gigabit ethernet controllers. This series implements
82576 emulation in particular. You can see the last patch for the documentation.

Note that there is another effort to bring 82576 emulation. This series was
developed independently by Sriram Yagnaraman.
https://lists.gnu.org/archive/html/qemu-devel/2022-12/msg04670.html

Patch 1 - 16 are general improvements for e1000 and e1000e.
Patch 17 - 18 are general improvements for e1000e test code.
Patch 19 - 21 makes necessary modifications to existing files.
Patch 22 starts off implementing igb emulation by copying e1000e code.
Patch 23 renames things so that it won't collide with e1000e.
Patch 24 makes building igb possible.
Patch 25 actually transforms e1000e emulation code into igb emulation.
Patch 26 - 27 makes modifications necessary for tests to existing files.
Patch 28 copies e1000e test code.
Patch 29 transforms e1000e test code into igb test code.
Patch 30 adds ethtool test automation.
Patch 31 adds the documentation.

The main reason why this series is so huge is that the early part of this series
includes general improvements for e1000e. They are placed before copying e1000e
code so we won't need to duplicate those changes for both of e1000e and igb code
later. As their utility do not depend on the igb implementation, they can be
merged earlier if necessary.

It is also possible to merge the work from Sriram Yagnaraman earlier than
patch 18+ and to cherry-pick useful changes from those patches later.

I think there are several different ways to get the changes into the mainline.
I'm open to any options.

Also be aware that most of e1000e patches are already sent to the mailing list.
