I'm unable to test any of the copper modes for the DP83869HM but according to the datasheet, autonegotiation should work in those. To be clear, "fiber mode" in the DP83869 linguo also includes 1000Base-X which can be used with a direct-attach copper cable. From what I've seen, autonegotiation is not supported in this configuration. Thanks, -- Romain Gantois, Bootlin Embedded Linux and Kernel engineering https://bootlin.com
