Hello, I want to know that why bridges are integrated. So,
I saw that GRE tunnels also established on br-int.
I dumped flowtables on br-int like bellow. (It's summerized )

Then, I assumed that by enabling OF1.3 protocol on OVS, they can use pipe-lining method by numbering Flowtable.
But, I could not know that what is the advantage of integration of both bridges
There are any performance improvement?
and second question is that packets which are putted tunnel are already transmitted to other host by marked flow-table
why it is addressed by "table=20"?
