Subject: [PATCH net-next 0/3] net: phy: dp83867: add cable diag support

This series adds more diagnostics of the physical medium to the DP83867.
The TDR reporting is similar to DP83869, so there might be some interest
in porting this changes to that driver.
The TDR reporting in PD83867 is divided into segments (from which a
cable length can be extracted). Because the reported lengths do not come
in regular intervals, when doing cable-test-tdr from ethtool, the value
of the reflection is reported, but not the length at which occurred
(even though the PHY reports it).
Likewise, the configuration of measurement lengths is also not
supported in this series, for the same reason (it is theoretically
possible to do it, with more complex configuration)

João Rodrigues (3):
  net: phy: dp83867: Add SQI support
  net: phy: dp83867: add cable test support
  net: phy: dp83867: Add support for amplitude graph
