It is true that this LOR is driver-specific but calling SIOCSIFMTU after acquiring a lock in lagg ioctl is not always safe.  Change of lladdr suffers from the same situation and it was solved by using an asynchronous task queue to update addresses on each port.  What do you think about piggybacking an MTU change to the queue by extending struct lagg_llq to a more generic one which makes it possible to handle per-port properties?
