V10 addresses a misnamed field in the ethtool spec, in patch 08/13. As a remainder, here's what the PHY listings would look like : - eth0 has a 88x3310 acting as media converter, and an SFP module with an embedded 88e1111 PHY - eth2 has a 88e1510 PHY # ethtool --show-phys * PHY for eth0: PHY index: 1 Driver name: mv88x3310 PHY device name: f212a600.mdio-mii:00 Downstream SFP bus name: sfp-eth0 PHY id: 0 Upstream type: MAC PHY for eth0: PHY index: 2 Driver name: Marvell 88E1111 PHY device name: i2c:sfp-eth0:16 PHY id: 21040322 Upstream type: PHY Upstream PHY index: 1 Upstream SFP name: sfp-eth0 PHY for eth2: PHY index: 1 Driver name: Marvell 88E1510 PHY device name: f212a200.mdio-mii:00 PHY id: 21040593 Upstream type: MAC Ethtool patches : https://github.com/minimaxwell/ethtool/tree/link-topo-v6 Link to V9: https://lore.kernel.org/netdev/20240228114728.51861-1-maxime.chevallier@bootlin.com/ Link to V8: https://lore.kernel.org/netdev/20240220184217.3689988-1-maxime.chevallier@bootlin.com/ Link to V7: https://lore.kernel.org/netdev/20240213150431.1796171-1-maxime.chevallier@bootlin.com/ Link to V6: https://lore.kernel.org/netdev/20240126183851.2081418-1-maxime.chevallier@bootlin.com/ Link to V5: https://lore.kernel.org/netdev/20231221180047.1924733-1-maxime.chevallier@bootlin.com/ Link to V4: https://lore.kernel.org/netdev/20231215171237.1152563-1-maxime.chevallier@bootlin.com/ Link to V3: https://lore.kernel.org/netdev/20231201163704.1306431-1-maxime.chevallier@bootlin.com/ Link to V2: https://lore.kernel.org/netdev/20231117162323.626979-1-maxime.chevallier@bootlin.com/ Link to V1: https://lore.kernel.org/netdev/20230907092407.647139-1-maxime.chevallier@bootlin.com/ Maxime Chevallier (13): net: phy: Introduce ethernet link topology representation net: sfp: pass the phy_device when disconnecting an sfp module's PHY net: phy: add helpers to handle sfp phy connect/disconnect net: sfp: Add helper to return the SFP bus name net: ethtool: Allow passing a phy index for some commands netlink: specs: add phy-index as a header parameter net: ethtool: Introduce a command to list PHYs on an interface netlink: specs: add ethnl PHY_GET command set net: ethtool: plca: Target the command to the requested PHY net: ethtool: pse-pd: Target the command to the requested PHY net: ethtool: cable-test: Target the command to the requested PHY net: ethtool: strset: Allow querying phy stats by index Documentation: networking: document phy_link_topology Documentation/netlink/specs/ethtool.yaml | 62 ++++ Documentation/networking/ethtool-netlink.rst | 46 +++ Documentation/networking/index.rst | 1 + .../networking/phy-link-topology.rst | 121 +++++++ MAINTAINERS | 2 + drivers/net/phy/Makefile | 2 +- drivers/net/phy/marvell-88x2222.c | 2 + drivers/net/phy/marvell.c | 2 + drivers/net/phy/marvell10g.c | 2 + drivers/net/phy/phy_device.c | 55 ++++ drivers/net/phy/phy_link_topology.c | 105 +++++++ drivers/net/phy/phylink.c | 3 +- drivers/net/phy/qcom/at803x.c | 2 + drivers/net/phy/qcom/qca807x.c | 2 + drivers/net/phy/sfp-bus.c | 15 +- include/linux/netdevice.h | 4 +- include/linux/phy.h | 6 + include/linux/phy_link_topology.h | 72 +++++ include/linux/phy_link_topology_core.h | 25 ++ include/linux/sfp.h | 8 +- include/uapi/linux/ethtool.h | 16 + include/uapi/linux/ethtool_netlink.h | 21 ++ net/core/dev.c | 9 + net/ethtool/Makefile | 2 +- net/ethtool/cabletest.c | 16 +- net/ethtool/netlink.c | 53 +++- net/ethtool/netlink.h | 10 + net/ethtool/phy.c | 297 ++++++++++++++++++ net/ethtool/plca.c | 19 +- net/ethtool/pse-pd.c | 13 +- net/ethtool/strset.c | 17 +- 31 files changed, 967 insertions(+), 43 deletions(-) create mode 100644 Documentation/networking/phy-link-topology.rst create mode 100644 drivers/net/phy/phy_link_topology.c create mode 100644 include/linux/phy_link_topology.h create mode 100644 include/linux/phy_link_topology_core.h create mode 100644 net/ethtool/phy.c -- 2.44.0 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
