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.

Vladimir Oltean (4):
  net: dsa: automatically bring up DSA master when opening user port
  net: dsa: automatically bring user ports down when master goes down
  Revert "net: Have netpoll bring-up DSA management interface"
  Revert "net: ipv4: handle DSA enabled master network devices"

Please treat this as RFC. There's still some debugging I need to do with
nfsroot.
