+         The raw CAN protocol option offers access to the CAN bus via
+         the BSD socket API. You probably want to use the raw socket in
+         most cases where no higher level protocol is being used. The raw
+         socket has several filter options e.g. ID masking / error frames.
+         To receive/send raw CAN messages, use AF_CAN with protocol CAN_RAW.
