From: Pantelis Koukousoulas Date: Thu, 19 Mar 2009 01:40:02 +0000 (-0700) Subject: virtio_net: Make virtio_net support carrier detection X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=4783256ef92f5aecd6d54693b16386f2a0021c2a;p=deliverable%2Flinux.git virtio_net: Make virtio_net support carrier detection Impact: Make NetworkManager work with virtio_net For now the semantics are simple: There is always carrier. This allows a seamless experience with e.g., qemu/kvm where NetworkManager just configures and sets up everything automagically. If/when a generally agreed-upon way to control carrier on/off in the emulator/hypervisor level emerges, it will be trivial to extend the driver to support that too, but for now even this 2-liner makes user experience that much better.
