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.
