[Qemu-devel] [RFC 0/4] virtio-net: Add support to MTU feature |

This series is based on on-going RFC from Aaron Conole which defines
a way for the host to expose its max MTU to the guest [0].
Using it, the guest can size its receive buffers accordingly, and if
GRO is disabled, can disable the mergeable buffers to improve performance.
In this version, the only way to pass the MTU relies on the added MTU protocol
feature, but it could also be done with a new property.
Thanks,
Maxime
