+Subject: [PATCH] lx2160acex7: SD1 protocol 8: revert dpmac link type back to
+ fixed
+
+On QSFP28 connector there is no sfp+ cage providing a linux phy object
+to each dpmac instance when configured as 4 individual NICs.
+This breaks the serdes driver logic for enabling and disabling serdes
+and can prevent link-up.
+
+Fixes: 6f13933: "lx2160acex7: upgrade network ports from fixed link to phy"
