Michal Kubecek says:

====================
ethtool netlink interface, part 3

Implementation of more netlink request types:

  - netdev features (ethtool -k/-K, patches 3-6)
  - private flags (--show-priv-flags / --set-priv-flags, patches 7-9)
  - ring sizes (ethtool -g/-G, patches 10-12)
  - channel counts (ethtool -l/-L, patches 13-15)

Patch 1 is a style cleanup suggested in part 2 review and patch 2 updates
the mapping between netdev features and legacy ioctl requests (which are
still used by ethtool for backward compatibility).

Changes in v2:
  - fix netdev reference leaks in error path of ethnl_set_rings() and
    ethnl_set_channels() (found by Jakub Kicinski)
  - use __set_bit() rather than set_bit() (suggested by David Miller)
  - in replies to RINGS_GET and CHANNELS_GET requests, omit ring and
    channel types not supported by driver/device (suggested by Jakub
    Kicinski)
  - more descriptive message size calculations in rings_reply_size() and
    channels_reply_size() (suggested by Jakub Kicinski)
  - coding style cleanup (suggested by Jakub Kicinski)
