([PATCH v2 00/26] e1000x cleanups (preliminary for IGB))

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

It is possible to merge the work from Sriram Yagnaraman and to cherry-pick
useful changes from this series later.

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

V2 -> V3:
- Rebased.
- Fixed PCIDevice reference in hw/net/igbvf.c.
- Fixed TX packet switching when VM loopback is enabled.
- Fixed VMDq enablement check.
- Fixed RX descriptor length parser.
- Fixed the definitions of RQDPC readers.
- Implemented VLAN VM filter.
- Implemented VT_CTL.Def_PL.
- Implemented the combination of VMDq and RSS.
- Noted that igb is tested with Windows HLK.

V1 -> V2:
- Spun off e1000e general improvements to a distinct series.
- Restored vnet_hdr offload as there seems nothing preventing from that.
