Please add net-next to the subject (the patch should also be based on that tree).
Also the "hyperv: " word should come first.
Like this:
[PATCH net-next] hyperv: Implement netvsc_get_channels() ethool op

On top part of this function, you also need to initialize max_chn = 1 around here:
        /* Initialize the rndis device */
        net_device = hv_get_drvdata(dev);
        net_device->num_chn = 1;

because the query for rsscap.num_recv_que is not done on all VSP versions.

Thanks,
