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().
