Some ethernet PHYs allow access to raw TDR data in addition to summary
diagnostics information. Add support for retrieving this data via
netlink ethtool. The basic structure in the core is the same as for
normal phy diagnostics, the PHY driver simply uses different helpers
to fill the netlink message with different data.

There is a graphical tool under development, as well a ethtool(1)
which can dump the data as text and JSON.

Thanks for Chris Healy for lots of testing.

  net: ethtool: Add attributes for cable test TDR data
  net: ethtool: Add generic parts of cable test TDR
  net: ethtool: Add helpers for cable test TDR data
  net: phy: marvell: Add support for amplitude graph
  net: ethtool: Allow PHY cable test TDR data to configured
  net : phy: marvell: Speedup TDR data retrieval by only changing page
    once
  net: phy: marvell: Configure TDR pulse based on measurement length
