Subject: [PATCH net-next 0/2] Introduce mlx5 ethernet timestamping

Hi Dave,

This patch series introduces the support for ConnectX-4 timestamping
and the PTP kernel interface.

First patch fixes a bug in SKB data pointer in device xmit function.
Second patch adds the needed low level helpers for:
	- Fetching the hardware clock (hardware internal timer)
	- Parsing CQEs timestamps
	- Device frequency capability

Added new en_clock.c file that handles all needed timestamping
operations:
	- Internal clock structure initialization.
	- PTP registration and cleanup.
	- PTP callbacks implementation.

Added the needed ioctl for setting/getting the current timestamping
configuration, and used this configuration in RX/TX data path to 
fill the SKB with the timestamp.

Eran Ben Elisha (2):
  net/mlx5_en: Restore the skb data pointer after xmit is finished
  net/mlx5_en: Add HW timestamping (TS) support
