Net-next:

int genphy_loopback(struct phy_device *phydev, bool enable)
{
      if (enable) {
          u16 val, ctl = BMCR_LOOPBACK;
          int ret;

          if (phydev->speed == SPEED_1000)
              ctl |= BMCR_SPEED1000;
          else if (phydev->speed == SPEED_100)
              ctl |= BMCR_SPEED100;

The problem happens in the speed change no matter it's forced or 
auto-neg in our device.

You say speed change. So do you just need to add support for 10Mbps,
so there is no speed change? Or are you saying phydev->speed does not
match the actual speed?
