Fixed-link PHY question

Fixed-link PHY question

[Gary Thomas]

I'm working with 2.6.33.3 on a MPC8358.  I'm trying to get it
to talk to a Marvell (DSA) switch which uses special drivers
and addressing to act like a PHY.  I have this working fine
on some older (2.6.28) systems by using a fixed-link PHY
descriptor in my device tree (using the TSEC on 8347).

The GETH driver calls 'of_phy_connect_fixed_link' which
always gives me this error:
   PHY 0:01 not found
   net eth1: Could not attach to PHY

How can I get the GETH driver to just accept the pseudo
PHY connection specified by
    fixed-link = <1 1 1000 0 0>;

Thanks

Figured it out - my ethernet node in the device tree has
to be called 'ethernet' for the fixed PHY emulation to see
the fixed-link properties.

Seems rather limited, but I don't have time to change it.
