[v4,5/6] vhost, vhost-user: Add VIRTIO_F_IN_ORDER to vhost feature bits

Commit Message

Jonah Palmer July 10, 2024, 12:55 p.m. UTC

Add support for the VIRTIO_F_IN_ORDER feature across a variety of vhost
devices.

The inclusion of VIRTIO_F_IN_ORDER in the feature bits arrays for these
devices ensures that the backend is capable of offering and providing
support for this feature, and that it can be disabled if the backend
does not support it.
