[ovs-dev] [PATCH v2 1/2] ovs-sandbox: add '--vswitchd-unforced-dummy' option.

[nickcooper-zhangtonghao]

The ovs-sandbox runs in the "dummy mode" by default.
In this mode of testing, no packets travel across
physical or virtual networks. But sometimes, we may
create veth network devices and add them to ovs bridge
for developing and testing. It's necessary to add an option.
