net: ethtool: Add generic parts of cable test TDR
Add the generic parts of the code used to trigger a cable test and return raw TDR data. 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. Miller <davem@davemloft.net>
