I do not understand where to store these packets in the kernel module, is there
a queue or buffer to store these packets?

If the packet can't match the flow table in the kernel module, it will be
delivered to ovs-vswitchd. Recv_upcalls() is a part of ovs-vswitchd, the number
of packets handled in recv_uopcalls()is UPCALL_MAX_BATCH(default is 50), could
you tell me the reason why it's designed so? thank you!
thank you!
I have another question.Is the ofpbuf stores the packets which are sent to
userspace, and the packets which have completed their in userspace and wait for
sent to datapath? I wish I had made it clear. Thank you for taking the time to
answer my questions.

I'm sorry I did not make it clear.
If a new packet arrive, the rx ssr will occupy the cpu and the process in
userspace has to stop, will it? So the thread which in userspace only can be
processed when there is no new packet arrival, am I right? thank you very much!

The queue where the packets are stored, , such as linux rx dma.

Dear friend:
hello,I am a graduated student in BJTU, China, my major is CS. I'm interested
in openvswitch, and i have a question. Could you tell me how many queues or
buffer are there in openvswitch , and what they are? I'm looking forward to
your reply. Thanks!
Sincerely yours,
