Tool/software:
Hi,
I've recently been testing the DP83869HM device using the upstreamed Linux driver. The upstream version of this driver enables auto-negotiation in 1000Base-X mode, while the datasheet for this part indicates that this is not supported:
>In fiber mode, the speed is not decided through auto-negotiation. Both sides of the link must be configured to the same operating speed.
In my testing, I have not seen the device work properly in this mode with auto-negotiation enabled.
I also note that the out of tree driver has auto-negotiation disabled: https://github.com/TexasInstruments/ti-ethernet-software/blob/main/linux_drivers/dp83869.c
What is the current recommended driver for use with 1000Base-X? If it is the out of tree driver, are there any plans to fix this in the upstream version?
Thanks.
