Implementing ndo_hwtstamp_get/set methods in netdevsim driver to use the newly introduced ndo_hwtstamp_get/setmake it respond to SIOCGHWTSTAMP/SIOCSHWTSTAMP IOCTLs. Also adding .get_ts_info ethtool method allowing to monitor HW timestamp configuration values set using SIOCSHWTSTAMP·IOCTL. Suggested-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Maxim Georgiev <glipus@gmail.com> --- Notes: Changes in v6: - Patch title was updated. No code changes. Changes in V4: - Implemented .get_ts_info·ethtool·method. - Tested the patch using hwstamp_ctl and ethtool: [root@centosvm kernel-net-next]# ethtool -T eni0np1 Time stamping parameters for eni0np1: Capabilities: software-transmit software-receive software-system-clock PTP Hardware Clock: none Hardware Transmit Timestamp Modes: none Hardware Receive Filter Modes: none [root@centosvm kernel-net-next]# hwstamp_ctl -i eni0np1 -t 1 -r 0 current settings: tx_type 0 rx_filter 0 new settings: tx_type 1 rx_filter 0 [root@centosvm kernel-net-next]# ethtool -T eni0np1 Time stamping parameters for eni0np1: Capabilities: software-transmit software-receive software-system-clock PTP Hardware Clock: none Hardware Transmit Timestamp Modes: off Hardware Receive Filter Modes: none [root@centosvm kernel-net-next]# hwstamp_ctl -i eni0np1 -t 1 -r 14 current settings: tx_type 1 rx_filter 0 new settings: tx_type 1 rx_filter 14 [root@centosvm kernel-net-next]# ethtool -T eni0np1 Time stamping parameters for eni0np1: Capabilities: software-transmit software-receive software-system-clock PTP Hardware Clock: none Hardware Transmit Timestamp Modes: off Hardware Receive Filter Modes: all some ptpv1-l4-event --- drivers/net/netdevsim/ethtool.c | 11 +++++++++++ drivers/net/netdevsim/netdev.c | 24 ++++++++++++++++++++++++ drivers/net/netdevsim/netdevsim.h | 1 + 3 files changed, 36 insertions(+)
