net: phy: micrel: ksz886x/ksz8081: add cabletest support
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. Signed-off-by: Oleksij Rempel <o.rempel@pengutronix.de> Signed-off-by: David S. Miller <davem@davemloft.net>
