Merge branch 'net-skip-taking-rtnl_lock-for-queue-get'
Jakub Kicinski says:
====================
net: skip taking rtnl_lock for queue GET (prep)
Skip taking rtnl_lock for queue GET ops on devices which opt
into running all ops under the instance lock. In preparating
for performing queue ops without rtnl lock clarify the protection
of queue-related fields.
