I noticed under your "FOR autonegation" section, there's a line that reads "the value of autonegation reg capable is 0". Is that local or remote end capability register? Do you have a scope? Can you verify if your sending FLPs if autonegotiation is enabled or MLT3 if you enabled 100MB. If aneg is enabled, can you break the link, verify with a scope you see FLPs, reattach the link, and see if it transitions from sending FLPs to MLT3/idle? Just for grins, have you tried enabling any loopbacks (client or line side) to verify communication?
