Merge branch 'net-use-netdev-lock-to-protect-napi'

====================
net: use netdev->lock to protect NAPI

We recently added a lock member to struct net_device, with a vague
plan to start using it to protect netdev-local state, removing
the need to take rtnl_lock for new configuration APIs.

Lay some groundwork and use this lock for protecting NAPI APIs.
