virtio_net: implements ethtool_ops.get_drvinfo
I often use "ethtool -i" command to check what driver controls the ehternet device. But because current virtio_net driver doesn't support "ethtool -i", it becomes the following: # ethtool -i eth3 Cannot get driver information: Operation not supported This patch simply adds the "ethtool -i" support. The following is the result when using the virtio_net driver with my patch applied to. # ethtool -i eth3 driver: virtio_net version: N/A firmware-version: N/A bus-info: virtio0 Personally, "-i" is one of the most frequently-used option, and most network drivers support "ethtool -i", so I think virtio_net also should do.
