Thanks for adding the patch in 5.6.x. I confirm that everything is
fine here wrt PCIe ethernet on jetson-tk1
But this patch isn't applied in master. I wish it would as the next
target to have the patch accepted is in kernel 5.9 at this time.
I would also like to bring attention to these patches (acked by
upstream tegra maintainer, might be scheduled):
Fix for sata enablement on jetson-tk1, (to be forwarded down to 5.6
Fix for nouveau firmware loading on tegra124 (gk20a) only master
(5.7/5.8?) might be affected:
Thanks for your advices.
