ethtool: provide channel counts with CHANNELS_GET request
Implement CHANNELS_GET request to get channel counts of a network device.
These are traditionally available via ETHTOOL_GCHANNELS ioctl request.
Omit attributes for channel types which are not supported by driver or
device (zero reported for maximum).
v2: (all suggested by Jakub Kicinski)
- minor cleanup in channels_prepare_data()
- more descriptive channels_reply_size()
- omit attributes with zero max count
