This is a regression since linux v4.19, introduced with commit 648e921888ad96ea3dc922739e96716ad3225d7f.

Without this patch, one ethernet port of this board is not usable.

From the currently maintained stable kernels, the patch 648e921888ad96ea3dc922739e96716ad3225d7f was also

backported to linux-4.14.y, so I suggest to backport the patch to v4.14 and v4.19+.

All now queued up, thanks.
