net: ethtool: netlink: Add support for triggering a cable test Add new ethtool netlink calls to trigger the starting of a PHY cable test.

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. When netlink ethtool is not part of the kernel configuration stubs are provided. It is also impossible to trigger a cable test, so the error code returned by the alloc function is of no consequence. v2: Include the status complete in the netlink notification message v4: Replace -EINVAL with -EMSGSIZE Signed-off-by: Andrew Lunn <andrew@lunn.ch> Reviewed-by: Michal Kubecek <mkubecek@suse.cz> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

ethtool: trim policy tables Since ethtool uses strict attribute validation there's no need to initialize all attributes in policy tables. 0 is NLA_UNSPEC which is going to be rejected. Remove the NLA_REJECTs.

This is particularly useful for PHYs that offer multiple diagnostic methods, such as Time Domain Reflectometry (TDR) and Active Link Cable Diagnostic (ALCD).
