hv_netvsc: Implement set_channels ethtool op
This enables the use of ethtool --set-channels devname combined N to change the number of vRSS queues. Separate rx, tx, and other parameters are not supported. The maximum is rsscap.num_recv_que. It passes the given value to rndis_filter_device_add through the device_info->num_chn field. If the procedure fails, it attempts to recover to the prior state. If the recovery fails, it logs an error and aborts. Current num_chn is saved and restored when changing the MTU. Signed-off-by:Andrew Schwartzmeyer <andschwa@microsoft.com> Reviewed-by:
