Many thanks for the patches. The termination patch should be commented by Vincent, who is currently pretty busy. But as the next merge windows is far away this can be managed in January. No hurry. The documentation is almost fine but still has error-signalling in the ip options and there's definitely no xl-cc-len16-dlc option. Please use the latest iproute2 code to generate the examples: https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/ Best regards, Oliver
