Let me rephrase.
Do these packet_in messages result from an OFPAT_OUTPUT action that
use OFPP_CONTROLLER as the output port?
Yes,
However, the reason code in the packet_in was OFPR_ACTION (0x01) rather
than OFPR_NO_MATCH (0x00).
I have investigated if some unexpected flow entries exists.
With my investigation, only the flow_mod of table-miss is accepted.
Other flow_mods for (NS, NA, ICMPv6 echo_req, ICMPv6 echo_rep) causesed
error with
the reason of "unsupported field type in the match". (I used only ping6
application for this investigation)
Therefore, I believe the switch has only one flow_entry of table-miss.

HI Ben,
Indeed, I could not answer you directly, since I had been a bit confused.
Sorry about that.
Here is my answer, I apologize if I have not understood your point
correctly.
Are these packets from flow misses or as a result of output to
OFPP_CONTROLLER?
(I guess, you mean "table-miss" with "flow miss").
Yes, it is the result of table-miss entry, since the controller put
only one entry, which has priority 0.
And it is output to OFPP_CONTROLLER (0xfffffffd).
(Is there any possibility to output packet_in other than OFPP_CONTROLLER?
I am understanding that all packet_in messages are output to
OFPP_CONTROLLER.
Am I correct? I was confused here.....)
I hope this answers to you correctly.

result from flow misses.

Hi Ben,
First, I need to say I am using OpenFlow 1.3.
I am relieved to hear OVS should buffer.
I guess there are some misunderstanding in my side.
But at least what I am facing is difference between
switch@trema-edge and ovs.
With same controller, the switch from trema-edge specifies buffer_id
while ovs does not.
I will send you the captured packets personally, I appreciate very
much for your investigataion.

I am now trying to run OVS of Kernel module with
Trema-edge(learning_switch code).
Both are in a box. (Ubuntu 12.10)
When I see the of13 packets, the buffer_id in packet_in messages are
0xffffffff(OPF_NO_BUFFER)
for both IPv4 packets and IPv6 packets.
Is it possible to make OVS buffer the packets?
OVS should be buffering packets. I am surprised to hear that it is
not.

OFPP_CONTROLLER? OVS only buffers packets that result from flow misses.
