Hi-
when I am testing DP83867IR phy Auto-Negotiation function,I encounter some questions,such as following
1. DP83867 connects PC with using 100M none crossover cable, PC(support 1000M/100M/10M) conifgs Auto-Negotiation, PC network interface displays net speed 100M,Duplex mode,but Device with DP83867 network interface status still 1000M, Duplex mode,why Device network interface speed not become 100M?
if manually configs PC netwoks speed 100M, after two seconds,Device (with DP83867) networks speed become 100M, if Device (with DP83867) connect 100M Port ethernet Switch or router, Device ethernet port
display speed 100M
Thank you for your assistance,
