net: pse-pd: Fix ethnl_pse_send_ntf() stub parameter type

2025-06-21T15:10:25+00:00

The ethnl_pse_send_ntf() stub function has incorrect parameter type when CONFIG_ETHTOOL_NETLINK is disabled. The function should take a net_device pointer instead of phy_device pointer to match the actual implementation.

net: pse-pd: Add support for reporting events

2025-06-19T02:00:15+00:00

Add support for devm_pse_irq_helper() to register PSE interrupts and report events such as over-current or over-temperature conditions. This follows a similar approach to the regulator API but also sends notifications using a dedicated PSE ethtool netlink socket.

ethtool: Add support for specifying information source in cable test results

2024-08-26T16:33:58+00:00

Enhance the ethtool cable test interface by introducing the ability to specify the source of the diagnostic information for cable test results. This is particularly useful for PHYs that offer multiple diagnostic methods, such as Time Domain Reflectometry (TDR) and Active Link Cable Diagnostic (ALCD). Key changes: - Added `ethnl_cable_test_result_with_src` and `ethnl_cable_test_fault_length_with_src` functions to allow specifying the information source when reporting cable test results. - Updated existing `ethnl_cable_test_result` and `ethnl_cable_test_fault_length` functions to use TDR as the default source, ensuring backward compatibility. - Modified the UAPI to support these new attributes, enabling drivers to provide more detailed diagnostic information.

net: ethtool: create and export ethtool_dev_mm_supported()

2023-04-14T05:22:10+00:00

Create a wrapper over __ethtool_dev_mm_supported() which also calls ethnl_ops_begin() and ethnl_ops_complete(). It can be used by other code layers, such as tc, to make sure that preemptible TCs are supported (this is true if an underlying MAC Merge layer exists).

net: ethtool: provide shims for stats aggregation helpers when CONFIG_ETHTOOL_NETLINK=n

2023-01-26T14:28:25+00:00

ethtool_aggregate_*_stats() are implemented in net/ethtool/stats.c, a file which is compiled out when CONFIG_ETHTOOL_NETLINK=n. In order to avoid adding Kbuild dependencies from drivers (which call these helpers) on CONFIG_ETHTOOL_NETLINK, let's add some shim definitions which simply make the helpers dead code. This means the function prototypes should have been located in include/linux/ethtool_netlink.h rather than include/linux/ethtool.h.

ethtool: fix ethtool msg len calculation for pause stats

2021-11-03T11:20:45+00:00

ETHTOOL_A_PAUSE_STAT_MAX is the MAX attribute id, so we need to subtract non-stats and add one to get a count (IOW -2+1 == -1).

This has no code changes, but it's a typo noticed in other clean-ups, so we might as well fix it. IS_ENABLED() takes full names, and should have the "CONFIG_" prefix.
