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 drivers/net/ethernet/mellanox/mlx5/core/Kconfig | 1 + drivers/net/ethernet/mellanox/mlx5/core/Makefile | 2 +- drivers/net/ethernet/mellanox/mlx5/core/en.h | 25 +++ drivers/net/ethernet/mellanox/mlx5/core/en_clock.c | 226 ++++++++++++++++++++ .../net/ethernet/mellanox/mlx5/core/en_ethtool.c | 32 +++ drivers/net/ethernet/mellanox/mlx5/core/en_main.c | 103 +++++++++- drivers/net/ethernet/mellanox/mlx5/core/en_rx.c | 9 + drivers/net/ethernet/mellanox/mlx5/core/en_tx.c | 16 ++ drivers/net/ethernet/mellanox/mlx5/core/main.c | 31 +++ .../net/ethernet/mellanox/mlx5/core/mlx5_core.h | 1 + include/linux/mlx5/device.h | 20 ++- include/linux/mlx5/mlx5_ifc.h | 5 +- 12 files changed, 464 insertions(+), 7 deletions(-) create mode 100644 drivers/net/ethernet/mellanox/mlx5/core/en_clock.c
