[PATCH v2 0/2] virtio-net: default_mtu - new conf. field
This set of two patches adds a new field called default_mtu to the configuration area of network devices. The motivation is to allow libvirt to set initial MTU different from 1500 on guests virtual NICs. We also propose to use this new field to report MTU changes by the guest OS to the device to facilitate debugging and mtu tunning. The first patch just clarify the definition of existing fields

[PATCH v2 1/2] virtio-net: rephrase devconf fields description
Clarify general description of the mac, status and max_virtqueue_pairs fields. Specifically, the old description is vague about configuration layout and fields offsets when some of the fields are non valid. Also clarify that validity of two status bits depends on two different feature flags. Signed-off-by: Victor Kaplansky <victork at redhat.com> --- content.tex | 42

[PATCH v2 2/2] virtio-net: add default_mtu configuration field
Sometimes it is essential for libvirt to be able to configure MTU on guest's NICs to a value different from 1500. The change adds a new field to configuration area of network devices. It will be used to pass initial MTU from the device to the driver, and to pass modified MTU from driver to the device when a new MTU is assigned by the guest OS. In addition, in order to support backward and
