Merge branch 'net-second-round-to-use-dev_net_rcu'
Eric Dumazet says:
====================
net: second round to use dev_net_rcu()
dev_net(dev) should either be protected by RTNL or RCU.
There is no LOCKDEP support yet for this helper.
Adding it would trigger too many splats.
This second series fixes some of them.
