Do you mean rtnl_lock when you say instance lock?

Search for the instance locks in Documentation/networking/netdevices.rst. We
essentially need to add netdev_ops_assert_locked to __dev_set_rx_mode
and make it work.

So, the handler should look something like this?

static void netif_write_rx_mode(struct work_struct *param) {
 rtnl_lock()
 netdev_lock()
 /* Processing */
netdev_unlock();
 rtnl_unlock();
}

v9 should be out by next week and fixes all the issues I could think
of so please wait for that
