+Subject: [PATCH 210/226] staging: fsl-dpaa2/mac: Fix unregister_netdev issue
+
+We only register the netdevice associated with a mac object if
+ONFIG_FSL_DPAA2_MAC_NETDEV is set, but we always unregister it
+during device remove(). Fix this by ifdef-ing the unregister
+operation.
+
+Also ifdef the change in netdevice name as it only makes sense
+under this option.
