This patch implements recently accepted by virtio-spec<br>
dynamic offloads configuration feature.<br>
See commit message for details.<br>

<br>
V2 changes:<br>
=A0 1. _GUEST_ added to command and feature names<br>
=A0 2. Live migration logic fixed<br>

Reported-by: Michael S. Tsirkin &lt;<a href=3D"mailto:mst@redhat.com">mst@r=

<br>
One of recently introduced Windows features (RSC)<br>
requires network driver to be able to enable and disable<br>
HW LRO offload on the fly without device reinitialization.<br>
<br>
Current Virtio specification doesn&#39;t support this requirement.<br>
The solution proposed by following spec patch is to add<br>
a new control command for this purpose.<br>
<br>
The same solution may be used in Linux driver for ethtool interface<br>
implementation.<br>
