Need to use 64bit variables for the calculation. - Modify the pd-92x0behavior in case of setting the current out of the available ranges. Report an error now. - Link to v1: https://lore.kernel.org/r/20240529-feature_poe_power_cap-v1-0-0c4b1d5953b8@bootlin.com Signed-off-by: Kory Maincent --- Kory Maincent (7): net: ethtool: pse-pd: Expand C33 PSE status with class, power and extended state netlink: specs: Expand the PSE netlink command with C33 new features net: pse-pd: pd692x0: Expand ethtool status message net: pse-pd: Add new power limit get and set c33 features net: ethtool: Add new power limit get and set features netlink: specs: Expand the PSE netlink command with C33 pw-limit attributes net: pse-pd: pd692x0: Enhance with new current limit and voltage read callbacks Documentation/netlink/specs/ethtool.yaml | 58 +++++ Documentation/networking/ethtool-netlink.rst | 87 +++++++- drivers/net/pse-pd/pd692x0.c | 317 ++++++++++++++++++++++++++- drivers/net/pse-pd/pse_core.c | 172 ++++++++++++++- include/linux/ethtool.h | 20 ++ include/linux/pse-pd/pse.h | 51 +++++ include/uapi/linux/ethtool.h | 191 ++++++++++++++++ include/uapi/linux/ethtool_netlink.h | 12 + net/ethtool/pse-pd.c | 119 +++++++++- 9 files changed, 997 insertions(+), 30 deletions(-) --- base-commit: b98d89947d124c8ca9150b32fdc0c5fb099243cf change-id: 20240425-feature_poe_power_cap-18e90ba7294b Best regards,
