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.
Best Regards,

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.
Are these packets from flow misses or as a result of output to
OFPP_CONTROLLER? OVS only buffers packets that result from flow misses.
