From: Ido Schimmel <idosch@nvidia.com> Patch #1 updates the UAPI headers. Patch #2 adds the actual implementation that allows user space to control transceiver modules' power mode. See the commit message for example output. Patches #3-#5 parse more fields from SFF-8636 and CMIS EEPROMs to provide better observability regarding the power mode of the modules. Patch #6 adds support for two new extended link states in order to allow user space to troubleshoot link down issues related to transceiver modules. See the commit message for example output. Ido Schimmel (6): Update UAPI header copies ethtool: Add ability to control transceiver modules' power mode ethtool: Print CMIS Module State ethtool: Print CMIS Module-Level Controls ethtool: Print SFF-8636 Power set and Power override bits ethtool: Add transceiver module extended states Makefile.am | 2 +- cmis.c | 87 ++++++++++++++++ cmis.h | 20 ++++ ethtool.8.in | 27 +++++ ethtool.c | 11 ++ netlink/desc-ethtool.c | 11 ++ netlink/extapi.h | 4 + netlink/module.c | 182 ++++++++++++++++++++++++++++++++++ netlink/monitor.c | 4 + netlink/netlink.h | 1 + netlink/settings.c | 12 +++ qsfp.c | 6 ++ qsfp.h | 2 +- shell-completion/bash/ethtool | 23 +++++ uapi/linux/ethtool.h | 36 ++++++- uapi/linux/ethtool_netlink.h | 34 ++++++- uapi/linux/if_link.h | 21 ++++ uapi/linux/net_tstamp.h | 17 +++- uapi/linux/netlink.h | 5 +- 19 files changed, 496 insertions(+), 9 deletions(-) create mode 100644 netlink/module.c
