Rename and handling write on socket using stream instead of specific method
Created special struct to handle bcm messages with can_frame and canfd_frame. We can now just send both of them seamlessly. Change-Id: Ia84e9cf2ab1dd0716cb09f6bb342a208e54f8e06 Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>
