v3 was here:
https://lists.gnu.org/archive/html/qemu-devel/2023-05/msg03607.html

Since then, I've incorporated lots of feedback from Vladimir:
 - split several patches into smaller pieces
 - use an enum to track various negotiation modes
 - reorder a few patches
 - several new patches (2, 5, 6)
 - other cleanups
