Hi,
I was looking at various things and I found that
do_xlate_actions() in ofproto.c was called way more often than I was
expecting. I'm using 1.1.0.
I set the following flows :
./ovs-ofctl add-flow tcp:127.0.0.1:6634
"priority=32769,idle_timeout=0,ip,nw_dst=15.144.110.1,action=mod_nw_tos:0,output:2"
./ovs-ofctl add-flow tcp:127.0.0.1:6634
"priority=32769,idle_timeout=0,ip,nw_dst=15.144.110.2,action=output:4"
I perform the following ping :
<jean@charolles>ping 15.144.110.1
PING 15.144.110.1 (15.144.110.1) 56(84) bytes of data.

^C
And this is how many time do_xlate_actions() is called for
the ToS flows during the ping :
Jun 02 11:08:15|00018|ofproto|ERR|do_xlate_actions() - setting ToS

Jun 02 11:08:35|00040|ofproto|ERR|do_xlate_actions() - setting ToS
^C
And this is how many subflows are created :
<opennet@valerian>./ovs-dpctl dump-flows dp0
in_port(3),eth(src=20:fd:f1:71:e3:91,dst=01:80:c2:00:00:00), packets:80,

packets:0, bytes:0, used:never, actions:2
Is this normal ?

Jean
