[ovs-dev] [async-msgs 00/13] allow better control over asynchronous messages

[Ben Pfaff]

OpenFlow has a number of "asynchronous" messages that switches generate
and send to controllers.  Until now, control over these has been ad-hoc.
This series makes it more systematic.

Ben Pfaff (13):
  ofproto: Allow service controllers to become masters and slaves.
  DESIGN: Document the properties of flow_mods.
  ovs-ofctl: Allow priority and timeout to be specified on mod-flows.
  connmgr: Do not persist OpenFlow settings from one session to
    another.
  ofp-util: Add struct ofputil_packet_out, helper functions, and use it
    all.
  Add support for parsing and printing OFPFF_* flags.
  ovs-ofctl: Add "packet-out" command.
  ovs-ofctl: New "ofctl/send" unixctl command.
  ovs-ofctl: New "ofctl/set-output-file" unixctl command.
  ofp-util: New function ofputil_encode_barrier_request().
  ovs-ofctl: New "ofctl/barrier" unixctl command.
  ofproto: Implement OpenFlow extension to allow control over async
    messages.
  vswitchd: Add "enable-async-messages" setting for controllers.
