To avoid memory waste, can add support for using an independent iob buffer
The IP protocol often configures CONFIG_IOB_BUFSIZE to be relatively large,
such as 512, for higher throughput. However, the buffer required by CAN is
fixed at a length of 16 or 64. If the system's IOB is directly used,
a lot of memory will be wasted.

Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

If the CAN stack receiving packets fast, but the application layer reading packets slow. Then `conn->readahead` will continue to grow, leading to memory leaks. Finally CAN stack potentially starve out all IOB buffers. To prevent memory leaks, users can restrict can socket buffer length.
