This is not a duplicate, bug was solved in the comments see comment 4 gigabut 5 because the drivers weren’t included in the distribution at all.
I also experience a situation on the mainline kernel where no link is detected upon plugging in the cable. In addition, there is no way to restore the factory default station address once the station address has been reprogrammed via eFuse. There are two known baseT link establishment issues with JMC25x.
This bug affects 6 people. This could have something to do with Energy Efficient Ethernet To Be Filled By O.

However it was fixable by downloading and manually compiling a new version of the jme drivers from here: See full activity log. The number of times that eFuse can be safely reprogrammed is 16 at most. Could you please test the latest upstream kernel available from the very top line at the top of the page the release names are irrelevant for testing, and please do not test the daily folder following https: Alex, please sudo lshw -c network and post output.

Also, if the length of the cable is longer than meters, the controller can not establish a baseT link. Use the lower nibble of the chip revision number to get the full mask revision of the controller. You need to log in to change this bug’s status. I’m at contro,ler loss here. Very definitely a JMC chipset wired ethernet controller in it, though.
