This patch support for cable test for the ksz886x switches and the
ksz8081 PHY.
The patch was tested on a KSZ8873RLL switch with following results:
- port 1:
- provides invalid values, thus return -ENOTSUPP
(Errata: DS80000830A: "LinkMD does not work on Port 1",
http://ww1.microchip.com/downloads/en/DeviceDoc/KSZ8873-Errata-DS80000830A.pdf)
- port 2:
- can detect distance
- can detect open on each wire of pair A (wire 1 and 2)
- can detect open only on one wire of pair B (only wire 3)
- can detect short between wires of a pair (wires 1 + 2 or 3 + 6)
- short between pairs is detected as open.
For example short between wires 2 + 3 is detected as open.
