The year is now 2025... As we say: "better late than never"! The first patch is a small clean up which fixes an incorrect statement concerning the CAN DLC, the second patch is the real thing and adds the documentation of how to use the ip tool to configure the TDC. Signed-off-by: Vincent Mailhol --- Changes in v2: - Fix below "make htmldocs" error: can.rst:1484: ERROR: Unexpected indentation. [docutils] - Change from "Bullet lists" to "Definition lists" format.
