This series unintentionally fix the bug because we are introducing a way
to split the packet depending on the buffer size ([PATCH 4/5] vhost/vsock:
split packets to send using multiple buffers) and we removed the limit
to 4K buffers ([PATCH 5/5] vsock/virtio: change the maximum packet size
allowed).

I discovered that there was a bug while we discussed memory accounting.

Do you think it's enough while we introduce the feature bit in the spec?

Thanks,
Stefano
