[issue40291] socket library support for CAN_J1939

[Karl Ding]

New submission from Karl Ding <karl.jw.ding at gmail.com>:

It would be nice to have support J1939 sockets.

Support for J1939 landed as part of the SAE J1939 SocketCAN patches, which are available after the Linux 5.4rc1 kernel. This is another protocol family for SocketCAN, much like the existing support for ISOTP and BCM.

Effectively, supporting this would hand off as much to the kernel as possible, which gives Python programs the ability deal with J1939 without having to implement the logic existing in the kernel in userspace.

This is provided to userspace [0] via the <linux/can/j1939.h> header.

I'd be happy to work on this and provide a PR.
