As we discussed before, "port mirroring" is bad naming. Yes, we should
use it, because that is what the datasheet calls this feature. But the
commit message should also contain a description of what this means,
and reference that the linux name for this concept is lane swapping.

Maybe give the 0 value a name. DP83867_PORT_MIRROING_KEEP?

That extra enum value can then make this more obvious:
if (dp83867->port_mirroring != DP83867_PORT_MIRROING_KEEP)
dp83867_config_port_mirroring(phydev);
On the first reading of the patch, i though you were setting mirroring
on/off under all conditions, but in fact you don't. This makes it
clearer.
Thanks
