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.
