Signed-off-by: Antonio Fischetti <antonio.fische...@intel.com> Acked by: Sugesh Chandran <sugesh.chand...@intel.com> --- In a firewall testbench set up with table=0, priority=1 actions=drop table=0, priority=10,arp actions=NORMAL table=0, priority=100,ct_state=-trk,ip actions=ct(table=1) table=1, ct_state=+new+trk,ip,in_port=1 actions=ct(commit),output:2 table=1, ct_state=+est+trk,ip,in_port=1 actions=output:2 table=1, ct_state=+new+trk,ip,in_port=2 actions=drop table=1, ct_state=+est+trk,ip,in_port=2 actions=output:1 I measured packet Rx rate in Mpps (regardless of packet loss). Bidirectional test with 64B UDP packets. 2 PMDs, 3 Tx q. I collected the following performance figures.
