Description (partial)

Symptom:
Ixia1—asr1k1---asr1k2---ixia2
Ixia1 sends 10000pps traffic to ixia2
ixia2 sends 10000pps traffic to ixia1
only normal ip traffic, without labal... and there is no packet lost
the qfp datapath utilization input and output should 20000
but the utilization summary displayed abnormal

Global Drop Stats                         Packets        Octets
----------------------------------------------------------------
   The Global drop stats were all zero

Conditions:
The test topology
Ixia1----asr1k_1-------------asr1k_2---------------ixia2

And I found the issue when I check the qfp load statistics
It ia a very simply test as below:
Just configure the ipv4 address between
ixia1---ars1k1 ; asr1k_1----asr1k_2; asr1k_2----ixia2
and set static route on asr1k_1 to ixia2;

set static route  on asr1k_2 to ixia1
ixia1 send traffic to ixia2 @10000pps, the source ip is ixia1 and the destination ip is ixia2
ixia2 send traffic to ixia1 @10000pps, the source ip is ixia2 and the destination ip is ixia1
I think the expect pps input and output should both be 20000 pps when attached summary
(if I was wrong ,pls correct me)
But actually there is only 10000 pps
