+Subject: [PATCH] net: dsa: move switchdev event implementation under the same
+ switch/case statement
+
+We'll need to start listening to SWITCHDEV_FDB_{ADD,DEL}_TO_DEVICE
+events even for interfaces where dsa_slave_dev_check returns false, so
+we need that check inside the switch-case statement for SWITCHDEV_FDB_*.
+
+This movement also avoids a useless allocation / free of switchdev_work
+on the untreated "default event" case.
