ethtool: provide ring sizes with RINGS_GET request
Implement RINGS_GET request to get ring sizes of a network device. These are traditionally available via ETHTOOL_GRINGPARAM ioctl request. Omit attributes for ring types which are not supported by driver or device (zero reported for maximum). v2: (all suggested by Jakub Kicinski) - minor cleanup in rings_prepare_data() - more descriptive rings_reply_size() - omit attributes with zero max size Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Reviewed-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.
