+          The CAN Gateway/Router is used to route (and modify) CAN frames.
+          It is based on the PF_CAN core infrastructure for msg filtering and
+          msg sending and can optionally modify routed CAN frames on the fly.
+          CAN frames can be routed between CAN network interfaces (one hop).
+          They can be modified with AND/OR/XOR/SET operations as configured
+          by the netlink configuration interface known e.g. from iptables.
