+Certain SFP modules (most notably Nokia GPON ones) first check
+connectivity on 1000base-x, and switch to 2500base-x afterwards. This
+is considered a quirk so the phylink switches the interface to
+2500base-x as well.
+
+However, after power-cycling the uDPU device, network interface/SFP module
+will not work correctly until the module is re-seated. This patch
+resolves this issue by forcing the interface to be brought up in
+2500base-x mode by default.
