Basic SyncE node defined in the ITU-T G.8264 consist of an Ethernet Equipment Clock (EEC) and have the ability to synchronize to reference frequency sources. This patch series is a prerequisite for EEC object and adds ability to enable recovered clocks in the physical layer of the netdev object. Recovered clocks can be used as one of the reference signal by the EEC. Further work is required to add the DPLL subsystem, link it to the netdev object and create API to read the EEC DPLL state. v5: - rewritten the documentation - fixed doxygen headers v4: - Dropped EEC_STATE reporting (TBD: DPLL subsystem) - moved recovered clock configuration to ethtool netlink v3: - remove RTM_GETRCLKRANGE - return state of all possible pins in the RTM_GETRCLKSTATE - clarify documentation v2: - improved documentation - fixed kdoc warning RFC history: v2: - removed whitespace changes - fix issues reported by test robot v3: - Changed naming from SyncE to EEC - Clarify cover letter and commit message for patch 1 v4: - Removed sync_source and pin_idx info - Changed one structure to attributes - Added EEC_SRC_PORT flag to indicate that the EEC is synchronized to the recovered clock of a port that returns the state v5: - add EEC source as an optiona attribute - implement support for recovered clocks - align states returned by EEC to ITU-T G.781 v6: - fix EEC clock state reporting - add documentation - fix descriptions in code comments Maciej Machnikowski (4): ice: add support detecting features based on netlist ethtool: Add ability to configure recovered clock for SyncE feature ice: add support for monitoring SyncE DPLL state ice: add support for recovered clocks Documentation/networking/ethtool-netlink.rst | 62 ++++ drivers/net/ethernet/intel/ice/ice.h | 7 + .../net/ethernet/intel/ice/ice_adminq_cmd.h | 70 ++++- drivers/net/ethernet/intel/ice/ice_common.c | 224 +++++++++++++++ drivers/net/ethernet/intel/ice/ice_common.h | 20 +- drivers/net/ethernet/intel/ice/ice_devids.h | 3 + drivers/net/ethernet/intel/ice/ice_ethtool.c | 96 +++++++ drivers/net/ethernet/intel/ice/ice_lib.c | 6 +- drivers/net/ethernet/intel/ice/ice_ptp.c | 35 +++ drivers/net/ethernet/intel/ice/ice_ptp_hw.c | 49 ++++ drivers/net/ethernet/intel/ice/ice_ptp_hw.h | 36 +++ drivers/net/ethernet/intel/ice/ice_type.h | 1 + include/linux/ethtool.h | 9 + include/uapi/linux/ethtool_netlink.h | 21 ++ net/ethtool/Makefile | 3 +- net/ethtool/netlink.c | 20 ++ net/ethtool/netlink.h | 4 + net/ethtool/synce.c | 267 ++++++++++++++++++ 18 files changed, 929 insertions(+), 4 deletions(-) create mode 100644 net/ethtool/synce.c
