Netra T1 105 hme0 woes ?

Hi there,

I am experimenting some woes about hme0 and Netra T1 model 105.

It is mostly working like a charm, but when I setup in /etc/rc.conf 100 
Full-Duplex operation mode (/sbin/ifconfig hme0 media 100BaseTX 
mediaopt full-duplex) the interface seems to not send any packets on 
the network.

But if I set as autodiscovery mode and after (in rc.local for example), 
the interface works like a charm...

It doesn't seems to be a bug inside hme drivers, but some strange arch 
on theses boxes :

---//--- (extract of /var/run/dmesg.boot)---

---//-----

As you can see there is *two* media interfaces on hme0 (ukphy0 and 
ukphy1)... I think that the system may take the first media interface 
that is not connected (or unexistant) on this platform.

Note that when opening this box, I can find a ethernet port near the 
CPU... Maybe this port is the ukphy0 and it is desactivated per default 
on Solaris ?

Thanks for any advices about that ... (do I need to send-pr about that 
?)
