net: phy: bcm54140: add cable diagnostics support
Use the generic cable tester functions from bcm-phy-lib to add cable
tester support.
100m cable, A/B/C/D open:
Cable test started for device eth0.
Cable test completed for device eth0.
Pair: Pair A, result: Open Circuit
Pair: Pair B, result: Open Circuit
Pair: Pair C, result: Open Circuit
Pair: Pair D, result: Open Circuit
Pair: Pair A, fault length: 106.60m
Pair: Pair B, fault length: 103.32m
Pair: Pair C, fault length: 104.96m
Pair: Pair D, fault length: 106.60m
1m cable, A/B connected, pair C shorted, D open:
Cable test started for device eth0.
Cable test completed for device eth0.
Pair: Pair A, result: OK
Pair: Pair B, result: OK
Pair: Pair C, result: Short within Pair
Pair: Pair D, result: Open Circuit
Pair: Pair C, fault length: 0.82m
Pair: Pair D, fault length: 1.64m
1m cable, A/B connected, pair C shorted with D:
Cable test started for device eth0.
Cable test completed for device eth0.
Pair: Pair A, result: OK
Pair: Pair B, result: OK
Pair: Pair C, result: Short to another pair
Pair: Pair D, result: Short to another pair
Pair: Pair C, fault length: 1.64m
Pair: Pair D, fault length: 1.64m
The granularity of the length measurement seems to be 82cm.
