&gt; &gt; &gt; In order to converge the discussion, maybe you can explain which one
&gt; &gt; &gt; of your 3 use cases and why can't work with _F_LEGACY_HEADER +
&gt; _F_LEGACY_MAC.
&gt; &gt; Hypervisor does not involve in feature negotiation and device life cycle phase
&gt; so it cannot negotiate it.
&gt; 
&gt; With  _F_LEGACY_HEADER + _F_LEGACY_MAC, hypervisor doesn't need to be
&gt; involved in the feature negotiation for modern devices as well.
&gt; 
Guest does not have this feature negotiation driver.
Hypervisor is not involved.
So, who negotiates?
