| 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.
