Hi Majid

Your guess is correct.

4294967295 is eqaul to 0xFFFFFFFF which indicates that the whole packet is 
contained in the packet-in message.

Subject: [ovs-discuss] receiving packet In with Buffer ID = 4294967295

hello
i have a host that sends 100 tcp syn packets per second which every packet has 
spoofed source IP and as a result they all will be sent to the POX controller. 
as i monitor by Wireshark i see that the first 250s packetIns have meaningful 
Bufffer ID value in packetin  but then i see lots of packetins which their 
Buffer id field equals to 4294967295 . i guess when a packetin with buffer id = 
4294967295  is sent to controller means that the openvswitch port has 
overflowed and as a result the packet can not be buffered in open vswitch and 
the whole packet is sent to controller.
is my guess right?
thank you
