net: Add struct kernel_ethtool_ts_info JIRA: https://issues.redhat.com/browse/RHEL-57750 commit 2111375b85ad173d58e7b8604246a3de60950ac8 Author: Kory Maincent <kory.maincent@bootlin.com> Date: Tue Jul 9 15:53:38 2024 +0200 net: Add struct kernel_ethtool_ts_info In prevision to add new UAPI for hwtstamp we will be limited to the struct ethtool_ts_info that is currently passed in fixed binary format through the ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code already started operating on an extensible kernel variant of that structure, similar in concept to struct kernel_hwtstamp_config vs struct hwtstamp_config. Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here we introduce the kernel-only structure in include/linux/ethtool.h. The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.

ethtool: add interface to interact with Ethernet Power Equipment Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2175237 commit 18ff0bcda6d1dd3d53b4ce3f03e61bf1a648f960 Author: Oleksij Rempel <linux@rempel-privat.de> Date: Mon Oct 3 08:52:00 2022 +0200 ethtool: add interface to interact with Ethernet Power Equipment Add interface to support Power Sourcing Equipment. At current step it provides generic way to address all variants of PSE devices as defined in IEEE 802.3-2018 but support only objects specified for IEEE 802.3-2018 104.4 PoDL Power Sourcing Equipment (PSE). Currently supported and mandatory objects are: IEEE 802.3-2018 30.15.1.1.3 aPoDLPSEPowerDetectionStatus IEEE 802.3-2018 30.15.1.1.2 aPoDLPSEAdminState IEEE 802.3-2018 30.15.1.2.1 acPoDLPSEAdminControl This is minimal interface needed to control PSE on each separate ethernet port but it provides not all mandatory objects specified in IEEE 802.3-2018. Since "PoDL PSE" and "PSE" have similar names, but some different values I decide to not merge them and keep separate naming schema. This should allow as to be as close to IEEE 802.3 spec as possible and avoid name conflicts in the future. This implementation is connected to PHYs instead of MACs because PSE auto classification can potentially interfere with PHY auto negotiation. So, may be some extra PHY related initialization will be needed. With WIP version of ethtools interaction with PSE capable link looks as following: $ ip l ... 5: t1l1@eth0: <BROADCAST,MULTICAST> .. ... $ ethtool --show-pse t1l1 PSE attributs for t1l1: PoDL PSE Admin State: disabled PoDL PSE Power Detection Status: disabled $ ethtool --set-pse t1l1 podl-pse-admin-control enable $ ethtool --show-pse t1l1 PSE attributs for t1l1: PoDL PSE Admin State: enabled PoDL PSE Power Detection Status: delivering power Signed-off-by: kernel test robot <lkp@intel.com> Signed-off-by: Oleksij Rempel <o.rempel@pengutronix.de> Reviewed-by: Bagas Sanjaya <bagasdotme@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Ivan Vecera <ivecera@redhat.com>

net: ethtool: netlink: retrieve stats from multiple sources (eMAC, pMAC) Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2175237 commit 04692c9020b76939715d6f2b4ff84d832246e0fc Author: Vladimir Oltean <vladimir.oltean@nxp.com> Date: Thu Jan 19 14:26:56 2023 +0200 net: ethtool: netlink: retrieve stats from multiple sources (eMAC, pMAC) IEEE 802.3-2018 clause 99 defines a MAC Merge sublayer which contains an Express MAC and a Preemptible MAC. Both MACs are hidden to higher and lower layers and visible as a single MAC (packet classification to eMAC or pMAC on TX is done based on priority; classification on RX is done based on SFD). For devices which support a MAC Merge sublayer, it is desirable to retrieve individual packet counters from the eMAC and the pMAC, as well as aggregate statistics (their sum). Introduce a new ETHTOOL_A_STATS_SRC attribute which is part of the policy of ETHTOOL_MSG_STATS_GET and, and an ETHTOOL_A_PAUSE_STATS_SRC which is part of the policy of ETHTOOL_MSG_PAUSE_GET (accepted when ETHTOOL_FLAG_STATS is set in the common ethtool header). Both of these take values from enum ethtool_mac_stats_src, defaulting to "aggregate" in the absence of the attribute. Existing drivers do not need to pay attention to this enum which was added to all driver-facing structures, just the ones which report the MAC merge layer as supported.
