Exactly. This approach is correct.
I even may tell you how to make this correctly, it was not made only because nobody was interested in this during 2.1.
Namely, dev->link_state is separate flag. When device feels that link state is down, it: - downs dev->link_state - ups dev->tbusy - broadcasts notification via netdev_chain (particularly, netlink catches it and notifies user level resetting IFF_RUNNING in the message, but not touching dev->flags.)
up event is: - ups dev->link_state - downs dev->tbusy, mark_bh(NET_BH) - broadcasts notification via netdev_chain (particularly, netlink catches it and notifies user level)
