NAME
     rte_tm_shaper_params

SYNOPSIS
     #include <rte_tm.h>

   Data Fields
     struct rte_tm_token_bucket committed
     struct rte_tm_token_bucket peak
     int32_t pkt_length_adjust
     int packet_mode

Detailed Description
     Shaper (rate limiter) profile

     Multiple  shaper instances can share the same shaper profile. Each node has
     zero or one private shaper (only one node using it)  and/or  zero,  one  or
     several  shared  shapers  (multiple  nodes use the same shaper instance). A
     private shaper is used to perform traffic shaping for a single node,  while
     a shared shaper is used to perform traffic shaping for a group of nodes.

     Single  rate shapers use a single token bucket. A single rate shaper can be
     configured by setting the rate of the committed bucket to zero,  which  ef-
     fectively	disables  this bucket. The peak bucket is used to limit the rate
     and the burst size for the current shaper.

     Dual rate shapers use both the committed and the peak  token  buckets.  The
     rate of the peak bucket has to be bigger than zero, as well as greater than
     or equal to the rate of the committed bucket.

   int32_t pkt_length_adjust
     Signed  value  to	be added to the length of each packet for the purpose of
     shaping. Can be used to correct the packet length with the framing overhead
     bytes that are also consumed on  the  wire  (e.g.	RTE_TM_ETH_FRAMING_OVER-
     HEAD_FCS). This field is ignored when the profile enables packet mode.

   int packet_mode
     When  zero,  the  byte mode is enabled for the current profile, so the rate
     and size fields in both the committed and peak token buckets are  specified
     in bytes per second and bytes, respectively. When non-zero, the packet mode
     is enabled for the current profile, so the rate and size fields in both the
     committed	and  peak  token buckets are specified in packets per second and
     packets, respectively.
