SESS_UCHKPT_CMD_UPDATE_DSK_FLOW_CHKPT_INFO
This micro-checkpoint is sent when a new NAT flow is created or deleted for a subscriber (while data is being
passed via the subscriber).
This checkpoint is sent from a timer but it is not timer based. The timer is used to pace (10 micro-checkpoints)
whenever the timer fires (granularity = 2 sec). This only occurs if there are new flows that need to be
micro-checkpointed. Otherwise, no micro-micro-checkpoints are sent.
