By the way, I was able to get this patch to work without using 4/49 by
changing the diff to net_client_init1() to be just the following:

I may end up using a modified version of your patch in my submission for
QMP netdev_add, while still avoiding the merge of NetdevLegacy (I'm not
sold on that one yet, because it exists only for the command line and
not for QMP, while we want to make QMP become typesafe).
