	  Say Y to have in-kernel support for j1939 socket type. This
	  allows communication according to SAE j1939.
	  The relevant parts in kernel are
	  SAE j1939-21 (datalink & transport protocol)
	  & SAE j1939-81 (network management).

Annotation

• Atlas domain: Networking Core / Sockets, Protocols, Packet Path, And Network Policy.
• Implementation status: atlas-only.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
