This patch calls into sock_cmsg_send() to parse the user supplied control information into a struct sockcm_cookie. Then assign the requested transmit time to the skb. This makes it possible to use the Earliest TXTIME First (ETF) packet scheduler with the CAN_RAW protocol. The user can send a CAN_RAW frame with a TXTIME and the kernel (with the ETF scheduler) will take care of sending it to the network interface.
