Snort 2.9 introduces the DAQ, or Data Acquisition library, for packet I/O. The
DAQ replaces direct calls to libpcap functions with an abstraction layer that
facilitates operation on a variety of hardware and software interfaces without
requiring changes to Snort. It is possible to select the DAQ type and mode
when invoking Snort to perform pcap readback or inline operation, etc. The
DAQ library may be useful for other packet processing applications and the
modular nature allows you to build new modules for other platforms.
