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>
