[RFC -next 0/2] virtio-net: Advised MTU feature
The following series adds the ability for a hypervisor to set an MTU on the
guest during feature negotiation phase. This is useful for VM orchestration
when, for instance, tunneling is involved and the MTU of the various systems
should be homogenous.
The first patch adds the feature bit as described in the proposed VFIO spec
