[PATCH 0/2] virtio-spec: dynamic network offloads configuration
From: Dmitry Fleytman <dfleytma 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.
