Subject: [PATCH net-next V1 0/4] Introduce mlx5 ethernet timestamping
Date: Thu, 17 Dec 2015 14:35:31 +0200	[thread overview]
Message-ID: <1450355735-30846-1-git-send-email-saeedm@mellanox.com> (raw)

Hi Dave,

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

This version addresses all the comments received on v0 and breaks 
the original series to four patches.

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

3rd patch adds new en_clock.c file that handles all needed timestamping
operations:
	- Internal clock structure initialization and other helper functions.
	- Added the needed ioctl for setting/getting the current timestamping
	  configuration.
	- used this configuration in RX/TX data path to fill the SKB with 
	  the timestamp.

4th patch Introduces PTP (PHC) support.

Eran Ben Elisha (4):
  net/mlx5e: Restore the skb data pointer after xmit is finished
  net/mlx5_core: Add support for reading hardware timestamp
  net/mlx5e: Add HW timestamping (TS) support
  net/mlx5e: Add PTP Hardware Clock (PHC) support
