Code Issues Proposed changes
deb-os-net-config/os_net_config/tests/test_objects.py
Sarath Kumar 15974244f6 Enable os-net-config to support and configure NFVSwitch 
These changes are to generate /etc/sysconf/network-scripts/ifcfg-* and
/etc/sysconfig/nfvswitch configuration files for nfvswitch and its interfaces.
NFVSwitch is a virtual switch implementation based on DPDK for datacenter
workloads with very high throughput needs.
