net: phy: micrel: ksz9031/ksz9131: add cabletest support
Add cable test support for Micrel KSZ9x31 PHYs.
Tested on i.MX8M Mini with KSZ9131RNX in 100/Full mode with pairs shuffled
before magnetics:
(note: Cable test started/completed messages are omitted)
mx8mm-ksz9131-a-d-connected$ ethtool --cable-test eth0
Pair A code OK
Pair B code Short within Pair
Pair B, fault length: 0.80m
Pair C code Short within Pair
Pair C, fault length: 0.80m
Pair D code OK
mx8mm-ksz9131-a-b-connected$ ethtool --cable-test eth0
Pair A code OK
Pair B code OK
Pair C code Short within Pair
Pair C, fault length: 0.00m
Pair D code Short within Pair
Pair D, fault length: 0.00m
Tested on R8A77951 Salvator-XS with KSZ9031RNX and all four pairs connected:
(note: Cable test started/completed messages are omitted)
r8a7795-ksz9031-all-connected$ ethtool --cable-test eth0
Pair A code OK
Pair B code OK
Pair C code OK
Pair D code OK
The CTRL1000 CTL1000_ENABLE_MASTER and CTL1000_AS_MASTER bits are not
restored by calling phy_init_hw(), they must be manually cached in
ksz9x31_cable_test_start() and restored at the end of
ksz9x31_cable_test_get_status().
