PFQ Kernel Module
PFQ is a Linux Kernel module for packet capture and functional processing, designed to be efficient on multi-core architectures. It's lock-less architecture provides performance similar to those of its competitors PF_RING-DNA and Netmap, while maintaining the total flexibility of the software and the full compatibility with a plethora of device drivers.
PFQ is able to capture as a network sniffer (as PF_PACKET), or through accelerated drivers obtained by simply recompiling the source codes though the pfq-omatic script. Software acceleration is done by overloading certain kernel symbols at compile time and providing more efficient implementations.
