+Subject: [PATCH] bcm63xx_enet: reset port link state in bcm_enetsw_open
+
+bcm_enetsw_open disables all ports, but does not reset their link state.
+This results in connected ports staying disabled after a ifdown/ifup
+cycle, since bcm_enetsw_phy_poll only enables them if their current state
+is different from the stored link state.
+
+Fix this by also resetting the port link state.
