Don't you need to check for dev_mac here as well?

I would prefer to have the enablement done inline here, instead of
scheduling a task.

It will be safer, given no one else is traversing the list and
accessing the element, given you have the target_list_lock in
netconsole_netdev_event, but, you don't have it in the resume_wq.

Given that we don't have a lock per target, target_list_lock is the
current lock protecting any simultaneous modification to the targets.
