everything seems to be fine with ethtool and mdio mux!
(I accidentally mixed up host and target consoles)

# ethtool eth0
Settings for eth0:
        Supported ports: [ TP MII ]
        Supported link modes:   10baseT/Half 10baseT/Full

                               drv probe link timer ifdown ifup
        Link detected: yes

But we do have some troubles with the internal PHY with Inochi's patches
on SG2000, the above "Link detected: yes" is actually without cable
inserted.
