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 process by numbering FlowTable.
but, I could not know that what is the advantage of integration of both bridges.
there are any performance improvement?
