Common case is 1 NCSI interface for server, we tested on this one and

Probably we missed that is softirq context which is obviously not a
place for rtnl_lock/unlock. Is there any other solution about except
delaying dev_set_mac_address in work queue? Or any suggestions about
how to deal with that in a proper way?

Nothing obvious comes to mind, unfortunately.
But the workqueue shouldn't be too bad.
