Hi,
This is my setup:
The topology like this: 82571EB-----tranceiver-----switch
I use e1000 driver at LINUX.
The 82571EB work at TBI mode, full duplex, send and respond to pause frame, hardware autonegotiation.
The tranceiver is a serdes interface copper SFP with 1000BASE-X auto-negotiation.
Question:
I want to establish a hardware based auto-negotiation.The 82571EB failed autonegotiation with other side,But I found it can reiceive config_word.
The 82571EB can't transmit or received packet in this situation, even if I forced link up.
Can anybody tell me how the auto-negotiation works with this controller?
Other thing:
I try to loopback under serdes in 82571EB, it normally worked.
I use another MAC chipset(VSC7344) with 1000BASE-X Serdes mode, connect with the same tranceiver,
the MAC chipset can auto-negotiation succeed and send/received packet with the other side.
Thanks
