Network card load balancing

In case your system has a network card with available load balancing features for sniffing you can activate the Network card load balancing that will trigger the usage of this feature as well as a series of optimizations. If this option is unset, then the load balancing between threads will be done by the kernel.

Activating this option is not recommended for virtual probes.
