Basic SyncE node defined in the ITU-T G.8264 consist of an Ethernet Equipment Clock (EEC) and have the ability to recover synchronization from the synchronization inputs - either traffic interfaces or external frequency sources. The EEC can synchronize its frequency (syntonize) to any of those sources. It is also able to select synchronization source through priority tables and synchronization status messaging. It also provides neccessary filtering and holdover capabilities This patch series introduces basic interface for reading the Ethernet Equipment Clock (EEC) state on a SyncE capable device. This state gives information about the source of the syntonization signal and the state of EEC. This interface is required to implement Synchronization Status Messaging on upper layers. Next steps: - add interface to enable source clocks and get information about them 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 Maciej Machnikowski (2): rtnetlink: Add new RTM_GETEECSTATE message to get SyncE status ice: add support for reading SyncE DPLL state drivers/net/ethernet/intel/ice/ice.h | 5 ++ .../net/ethernet/intel/ice/ice_adminq_cmd.h | 34 +++++++++ drivers/net/ethernet/intel/ice/ice_common.c | 62 ++++++++++++++++ drivers/net/ethernet/intel/ice/ice_common.h | 4 + drivers/net/ethernet/intel/ice/ice_devids.h | 3 + drivers/net/ethernet/intel/ice/ice_main.c | 55 ++++++++++++++ drivers/net/ethernet/intel/ice/ice_ptp.c | 35 +++++++++ drivers/net/ethernet/intel/ice/ice_ptp_hw.c | 44 +++++++++++ drivers/net/ethernet/intel/ice/ice_ptp_hw.h | 22 ++++++ include/linux/netdevice.h | 6 ++ include/uapi/linux/if_link.h | 43 +++++++++++ include/uapi/linux/rtnetlink.h | 3 + net/core/rtnetlink.c | 74 +++++++++++++++++++ security/selinux/nlmsgtab.c | 3 +- 14 files changed, 392 insertions(+), 1 deletion(-)
