Hi Ben, handle_upcalls() is the function in userspace, which handles packets queued from kernel space. handle_upcall() does a dpif_rcv().
Thanks, Anoob.

But i cant seem to find where this is received? I saw a similar massage stating that it is collected by "dpif_linux_recv()". It is my understanding that if a packet cannot be matched to a flow it is sent to userspace to see if it can be matched to a flow, but i cant see anything familiar to this in "dpif_linux_recv()". Can anyone tell me where i might find this part of the code? Thanks Ben
