...n <dfleytma at redhat.com> V2 changes: 1. _GUEST_ added to command and feature names 2. Live migration logic fixed Reported-by: Michael S. Tsirkin <mst at redhat.com> One of recently introduced Windows features (RSC) requires network driver to be able to enable and disable HW LRO offload on the fly without device reinitialization. Current Virtio specification doesn't support this requirement. The solution proposed by following spec patch is to add a new control command for this purpose. The same solution may be used in Linux driver for ethtool interface implementation. Patch...
