Subject: Re: [RFC v2 -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
