From cda5c15b23fb9d683a491e8bd137d11d8552ac02 Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Mon, 7 Dec 2015 13:57:35 +0100 Subject: net: dsa: move dsa slave destroy code to slave.c Move dsa slave dedicated code from dsa_switch_destroy to a new dsa_slave_destroy function in slave.c. Add the netif_carrier_off and phy_disconnect calls in order to correctly cleanup the netdev state and PHY state machine.
