+Subject: [PATCH 208/208] b44: use fixed PHY device if we do not find any
+
+The ADM6996L switch and some Broadcom switches with two MII interfaces
+like the BCM5325F connected to two MACs on the SoC, used on some
+routers do not return a valid value when reading the PHY id register
+and Linux thinks there is no PHY at all, but that is wrong.
+This patch registers a fixed phy in the arch code and then searches it
+when there is no other phy in the Ethernet driver code.
