The requested average rate of the flow. The base unit of this
object is 1 kilo-bits per second. 0 may be specified for a
rate which causes all packets to be out-of-profile.
Out-of-profile indicates that a packet causes the committed
access rate of the packet's flow to be exceeded. Committed
access rate is the bandwidth that has been committed to a
specific flow or group of flows. The committed rate can be
enforced by policing or by shaping.
