Thanks. I thought I was being diligent, and I ran MAKEALL, but I guess it wasn't enough. >> diff --git a/drivers/net/xilinx_axi_emac.c b/drivers/net/xilinx_axi_emac.c >> index 7854a04..d777144 100644 >> --- a/drivers/net/xilinx_axi_emac.c >> +++ b/drivers/net/xilinx_axi_emac.c >> @@ -272,7 +272,11 @@ static int setup_phy(struct eth_device *dev) >> phydev->advertising = phydev->supported; >> priv->phydev = phydev; >> phy_config(phydev); >> - phy_startup(phydev); >> + if (phy_startup(phydev)) { >> + printf("axiemac: could not initialize PHY %s\n", >> + phydev->dev->name); >> + return 0; >> + } >> >> switch (phydev->speed) { >> case 1000: > > Why doesn't this driver use a ret variable? > Other driver's patch used this. Because setup_phy() returns either 0 (failure) or 1 (success).

Now that phy_startup() can return an actual error code, check for that error code and abort network initialization if the PHY fails.
