====================
Automatically manage DSA master interface state

This patch series adds code that makes DSA open the master interface
automatically whenever one user interface gets opened, either by the
user, or by various networking subsystems: netconsole, nfsroot.
With that in place, we can remove some of the places in the network
stack where DSA-specific code was sprinkled.
