This provides a sample application and library showing how to use the Intel(R) DPDK with basic netmap applications. The Netmap compatibility library provides a minimal set of APIs to give the ability to programs written against the Netmap APIs to be run with minimal changes to their source code, using the Intel® DPDK to perform the actual packet I/O. Since Netmap applications use regular system calls, like open(), ioctl() and mmap() to communicate with the Netmap kernel module performing the packet I/O, the compat_netmap library provides a set of similar APIs to use in place of those system calls, effectively turning a Netmap application into a Intel(R) DPDK one. The provided library is currently minimal and doesn’t support all the features that Netmap supports, but is enough to run simple applications, such as the bridge example included. The application requires a single command line option: -i INTERFACE is the number of a valid Intel(R) DPDK port to use. If a single -i parameter is given, the interface will send back all the traffic it receives. If two -i parameters are given, the two interfaces form a bridge, where traffic received on one interface is replicated and sent by the other interface.
