Alfredo, I have developed non-zc system where two processes working with one network interface independently using pfring_* API, and I want to migrate to pfring-zc. But if one process opens interface, other process can't open same device with error "Device or resource busy".
Can I use one network interface independently in two processes in zc mode?
