Hi Dave,
This patch series introduces the support for ConnectX-4 timestamping
and the PTP kernel interface.
Changes from V2:
net/mlx5_core: Introduce access function to read internal_timer
- Remove one line function
- Change function name
net/mlx5e: Add HW timestamping (TS) support:
- Data path performance optimization (caching tstamp struct in rq,sq)
- Change read/write_lock_irqsave to read/write_lock
- Move ioctl functions to en_clock file
- Changed overflow start algorithm according to comments from Richard
- Move timestamp init/cleanup to open/close ndos.
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.
