This adds documentation for DPDK netdev to do an IVSHMEM shared memory to host
app or VM app
test using current OVS code. This example allows people to do learn how it is
done, so that they can
develop their own shared IVSHMEM memory applications. Also adds knowledge to
better system
setup for
SHMEM?

Corrected DPDK queue size to be a power of 2 which allows dpdkr interface to be

Increased queue size to improve zero loss data rate.
Changed NIC queue size comment to make NIC queue size formula more clear.

Eliminated the inside polling loop SMP TX output lock (DPDK queue handles SMP).

This is to give a hint of what values the defined value can be set to.

Put in a DPDK queue to receive from multiple core SMP input from vSwitch for
NIC TX output.
Eliminated the inside polling loop SMP TX output lock (DPDK queue handles SMP).
Added a SMP lock for non-polling operation to allow TX output by the
non-polling thread

The idle timeout of 1.5 seconds for exact match flows creates big problems for
testing. I suspect that other than for internal generated flows within the

Also another question. Does this patch result in a measurable improvement in
any
