• Detected declarations: `enum devlink_command`, `enum devlink_port_type`, `enum devlink_sb_pool_type`, `enum devlink_sb_threshold_type`, `enum devlink_eswitch_mode`, `enum devlink_eswitch_inline_mode`, `enum devlink_eswitch_encap_mode`, `enum devlink_port_flavour`, `enum devlink_rate_type`, `enum devlink_param_cmode`.
• Atlas domain: Core OS / Core Kernel Interface.
• Implementation status: source implementation candidate.

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.
