net: ethtool: netlink: Add support for triggering a cable test Add new ethtool netlink calls to trigger the starting of a PHY cable test. Add Kconfig'ury to ETHTOOL_NETLINK so that PHYLIB is not a module when ETHTOOL_NETLINK is builtin, which would result in kernel linking errors. v2: Remove unwanted white space change Remove ethnl_cable_test_act_ops and use doit handler Rename cable_test_set_policy cable_test_act_policy Remove ETHTOOL_MSG_CABLE_TEST_ACT_REPLY v3: Remove ETHTOOL_MSG_CABLE_TEST_ACT_REPLY from documentation Remove unused cable_test_get_policy Add Reviewed-by tags v4: Remove unwanted blank line Signed-off-by: Andrew Lunn <andrew@lunn.ch> Reviewed-by: Michal Kubecek <mkubecek@suse.cz> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

net: ethtool: Add infrastructure for reporting cable test results Provide infrastructure for PHY drivers to report the cable test results. A netlink skb is associated to the phydev. Helpers will be added which can add results to this skb. Once the test has finished the results are sent to user space.

Any PHY driver which support this must implement the new driver op. Signed-off-by: Andrew Lunn <andrew@lunn.ch> v2 Update nxp-tja11xx for API change. Signed-off-by: David S.

net: ethtool: Allow PHY cable test TDR data to configured Allow the user to configure where on the cable the TDR data should be retrieved, in terms of first and last sample, and the step between samples. Also add the ability to ask for TDR data for just one pair. If this configuration is not provided, it defaults to 1-150m at 1m intervals for all pairs. Signed-off-by: Andrew Lunn <andrew@lunn.ch> v3: Move the TDR configuration into a structure Add a range check on step Use NL_SET_ERR_MSG_ATTR() when appropriate Move TDR configuration into a nest Document attributes in the request Signed-off-by: David S.
