I'm not sure if it's a different model or not -- I do not know whether the
82545 has the internal SERDES or only an MII interface (or whether it
has no externally exposed MII interface but only an integrated makphy).

A SERDES is not an miibus PHY.  If the driver finds a PHY on the MII,
you are not using the SERDES.

I think the point is, if you have a fibre wm card with 82545 controller, it
will almost certainly not work, since we only support the MII on these
particular chips, not the SERDES interface (which is only used for fibre).

It would probably be best to check the datasheet before saying anything too
specific in the manual page.  Sadly it will likely be confusing no matter
how carefully written it is.
