Hi,
I don't know why but it looks that this series wasn't showing up in the
list for some reason. Only the recipients in the To or Cc lines seemed
able to get it. Would it be possible to fix the mail client or include
me to the thread for review?
Thanks,
-Siwei

Add a new operation to allow a vDPA device to be resumed after it has
been suspended. Trying to resume a device that wasn't suspended will
result in a no-op.
This operation is optional. If it's not implemented, the associated
backend feature bit will not be exposed. And if the feature bit is not
exposed, invoking this operation will return an error.
