Hello Dan, just a few coding style fixes:

> +static int dp83811_set_wol(struct phy_device *phydev,
> +			   struct ethtool_wolinfo *wol)
> +{
> +	struct net_device *ndev = phydev->attached_dev;
> +	u16 value;
> +	const u8 *mac;

Please order local variables longest to shortest line.

> +static void dp83811_get_wol(struct phy_device *phydev,
> +			    struct ethtool_wolinfo *wol)
> +{
> +	int value;
> +	u16 sopass_val;

Likewise.

> +static int dp83811_config_aneg(struct phy_device *phydev)
> +{
> +	int err;
> +	int value;

Likewise.

However, I would recommend that in these functions having two
integer local variables that you just declare them both on the
same line like:

	int err, value;

> +static int dp83811_config_init(struct phy_device *phydev)
> +{
> +	int err;
> +	int value;

Likewise.

Thank you.
