 +The ''driver'' block ensures that various offload parameters are turned off for the host and guest which is deemed to be good practice for virtio interfaces on a bridge. Additionally, the bridge can be configured to turn off most of the offloading:
 +<code bash>
 +ethtool -K br0 tso off sg off ufo off gro off gso off
 +</code>
 +where:
 +  * ''br0'' is the bridge interface to which the virtio interfaces are added.
