Marvell MV6281 OpenRD client mge1

[Matthias Reyelt]

Hi,

I have changed the PHY address for mge1 to 0x18 in the code, and the second 
PHY is now correctly detected. I can ifconfig the interface and I am able to 
receive packets. I am not able to send packets yet. 

If I ping mge1 over the network tcpdump reports the ARP requests and it 
reports the ARP replies as well. The replies do not reach the cable though. 
(They aren't sent to mge0 either). 
I haven't yet found out, where the packets get lost, they seem to pass 
mge_start_locked() correctly. I will check the register settings.  

Matthias
