Hi Andy,

I still think it should just be a property of the ethernet node.  We
aren't describing the TBI, we're describing a setting for the
ethernet controller's register.

Like this?  Do we need to have one for each ethernet@xxxxxx?

Scott and I have been talking, and right now it seems like a better
idea might be to have the TBI address get assigned dynamically, based
on where PHYs aren't.

It's non-trivial to do (though not difficult), but this way we won't
have to regret creating a bad interface.  You just need to look at
the mdio bus, and find out which addresses responded.  Then you
create a variable in the gfar_private structure to hold what it gets
set to, and make sure that gfar_configure_serdes uses that value
instead of the TBIPA constant.

Sounds like a good plan.  I'll try to put something together and post for
comments.

Thanks,
Joe
