       CHOKe (CHOose and Keep for responsive flows, CHOose and Kill for  unre-
       sponsive  flows)  is  a  classless  qdisc designed to both identify and
       penalize flows that monopolize the queue. CHOKe is a variation of  RED,
       and the configuration is similar to RED.

       Once  the queue hits a certain average length, a random packet is drawn
       from the queue. If both the to-be-queued and the drawn packet belong to
       the same flow, both packets are dropped. Otherwise, if the queue length
       is still below the maximum length, the new packet  has  a  configurable
       chance  of  being marked (which may mean dropped).  If the queue length
       exceeds max, the new packet will always be marked (or dropped).  If the
       queue length exceeds limit, the new packet is always dropped.

       The  marking  probability  computation  is  the same as used by the RED

       The parameters are the same as for RED,  except  that  RED  uses  bytes
       whereas choke counts packets. See tc-red(8) for a description.
