[PATCH v2 0/4] virtio-net: Convert feature properties to OnOffAuto

[Akihiko Odaki]

Based-on: <20240428-rss-v10-0-73cbaa91aeb6@daynix.com>
("[PATCH v10 00/18] virtio-net RSS/hash report fixes and improvements")

Some features are not always available, and virtio-net used to disable
them when not available even if the corresponding properties were
explicitly set to "on".

Convert feature properties to OnOffAuto so that the user can explicitly
tell QEMU to automatically select the value by setting them "auto".
QEMU will give an error if they are set "on".
