====================
convert net drivers to ndo_hwtstamp API part 1

This is part 1 of patchset to convert drivers which support HW
timestamping to use .ndo_hwtstamp_get()/.ndo_hwtstamp_set() callbacks.
The new API uses netlink to communicate with user-space and have some
test coverage. Part 2 will contain another 6 patches from v1 of the
series.
There are some drivers left with old ioctl interface after this series:
- mlx5 driver be shortly converted by nVidia folks
- TI netcp ethss driver which needs separate series which I'll post
  after this one.
