Subject[PATCH net-next 0/4] net: phy: broadcom: cable tester support
Date
Add cable tester support for the Broadcom PHYs. Support for it was
developed on a BCM54140 Quad PHY which RDB register access.

If there is a link partner the results are not as good as with an open
cable. I guess we could retry if the measurement until all pairs had at
least one valid result.

Please note that this patch depends on Andrew's latest cable testing
series:
