[PATCH v2 net-next 0/3] Implement PTP support in netdevsim

This patchset adds support to the PTP HW timestamping emulation in the
netdevsim. It uses existing binding between netdevsim and ptp_mock
driver to generate transmit and receive timestamps.

It also adds the selftest to verify the hw timestamping functionality
running over netdevsim.

v2:
- Added selftest/net/ptp.sh
- Modified ptp_mock to use spin_lock_bh
- Populate ethtool defaults using ethtool_op_get_ts_info

Maciek Machnikowski (3):
  ptp_mock: Expose ptp_clock_info to external drivers
  netdevsim: Implement basic ptp support
  selftests:net: Implement ptp4l sync test using netdevsim
