Our projects have the requirement of eth0/1 use 100BaseT. eth0 or eth1 connect to 100baseT wire, ar8033 auto-negotiation to 100base,  after execute  command the operation of eth down and up, link is not ok, kernel print:   803x_aneg_done: SGMII link is not ok.  I also try to configure the phy work on 100baseT full duplex  force mode, though it looks fine, actually sgmii is still not ok. 

can anyone give me some suggestions? Thanks.
