Iproute2 development is closely tied to Linux kernel networking development. Most new features require a kernel and a utility component. Please submit both to the Linux networking mailing list <netdev@vger.kernel.org> The current source is in the git repository: git://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git The master branch contains the source corresponding to the current code in the mainline Linux kernel (ie follows Linus). The net-next branch is a temporary branch that tracks the code intended for the next release; it corresponds with networking development branch in the kernel.
