Commit 448b4482c671 ("net: dsa: Add lockdep class to tx queues to avoid
lockdep splat") removed the netif_device_detach() call done in
dsa_slave_suspend() which is necessary, and paired with a corresponding
netif_device_attach(), bring it back.
Fixes: 448b4482c671 ("net: dsa: Add lockdep class to tx queues to avoid lockdep splat")
