Why emphasize input set 'src MAC address and dst MAC address' and ' dst MAC address ' as input set?
Can't we support src MAC only?
When OVS-DPDK is working as a pure L2 switch, Both two ways

What's the enumeration's purpose?
Could you follow the original code for input set configuration and packet construct?
