+Subject: [PATCH 19/63] NET: bcm63xx_enet: move phy_(dis)connect into probe/remove
+
+Only connect/disconnect the phy during probe and remove, not during any
+open/close. The phy seldom changes during the runtime, and disconnecting
+the phy during close will prevent it from keeping any configuration over
+a down/up cycle.
