packet-in high priority cannot be sent to ODL when TCP buffer on the OFS is congested .
Yes lib/stream-tcp.c has the code but i have to hand-tune  from ovs-vsctl binary.

What are you really trying to accomplish?  It isn't usually useful to
hand-tune TCP buffer sizes.

lib/stream-tcp.c has the code that opens and accepts TCP connections,
so that might be a good place to adjust buffer size.
