* Deprecation of Models (Miroslav)  (abhijitkumbhare, 15:08:07)
  * Bug/task to deprecate notifications  (abhijitkumbhare, 15:08:53)
  * shuva notes that we had decided to keep the flow removed
    notifications (needed by VTN & VPN services)  (abhijitkumbhare,
    15:10:18)
  * jbacigal thinks that notifications could have problems regarding the
    performance and other issues, Vinayak thinks the lack of
    notifications can lead to performance problems  (abhijitkumbhare,
    15:16:49)
  * One of the problems is that notifications can arrive out of order -
    which the applications need to handle. Vinayak thinks that is an
    acceptable tradeoff to the applications  (abhijitkumbhare, 15:17:50)
  * Vinayak says we already have a knob to have notifications or not
    (abhijitkumbhare, 15:19:52)
  * Actually, it was decided to use the FLOW_MOD message flag to
    register for Flow Removal notification  (ManoharSL, 15:21:40)
  * If an particular NSF does not need the notification, then it has to
    not ask for flow removed notification  (ManoharSL, 15:22:16)
  * by setting the flag in FLOW_MOD message itself  (ManoharSL,
    15:22:27)
  * The flag name is: OFPFF_SEND_FLOW_REM  (abhijitkumbhare, 15:24:38)
  * Miroslav says the reason for removing notifications is to have a
    clean API and only have a single channel  (abhijitkumbhare,
    15:24:49)
  * need to measure the cost of turning notification off and turning
    statistics on for large use-cases liek a million flows  (shuva,
    15:31:03)
  * AGREED: We will be going with the knob for Carbon  (abhijitkumbhare,
    15:33:59)

* Feature reorganization  (abhijitkumbhare, 15:34:35)
  * anleitne says nothing special with respect to feature reorganization
    (abhijitkumbhare, 15:35:03)
