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
