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 v1. The first patch
was replaced with a one that addresses the SKB data issue and fixes it
in the right way (By Achiad), Also Addressed all of Richard's comments
re timestamping patches and fixed the delayed work to work in the correct delay.
In details:
1st patch prevents the driver from modifying skb->data and SKB CB in
device xmit function.
2nd 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.
Achiad Shochat (1):
net/mlx5e: Do not modify the TX SKB
Eran Ben Elisha (3):
net/mlx5_core: Add support for reading hardware timestamp
net/mlx5e: Add HW timestamping (TS) support
net/mlx5e: Add PTP Hardware Clock (PHC) support
