VDPA Debug/Statistics

[Eli Cohen]

Hi All

Currently, the only statistics we get for a VDPA instance comes from the virtio_net device instance. Since VDPA involves hardware acceleration, there can be quite a lot of information that can be fetched from the underlying device. Currently there is no generic method to fetch this information.

One way of doing this can be to create a the host, a net device for each VDPA instance, and use it to get this information or do some configuration. Ethtool can be used in such a case

I would like to hear what you think about this or maybe you have some other ideas to address this topic.

Thanks,
Eli
