Why This File Exists

Networking stack implementation surface: socket APIs, protocol dispatch, packet flow, routing, filtering, and network namespaces.

• Networking stack implementation surface: socket APIs, protocol dispatch, packet flow, routing, filtering, and network namespaces.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/types.h

Detected Declarations

• struct ncsi_dev
• function ncsi_vlan_rx_add_vid
• function ncsi_vlan_rx_kill_vid
• function void
• function ncsi_start_dev
• function ncsi_stop_dev

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct ncsi_dev`, `function ncsi_vlan_rx_add_vid`, `function ncsi_vlan_rx_kill_vid`, `function void`, `function ncsi_start_dev`, `function ncsi_stop_dev`.
• Atlas domain: Networking Core / Sockets, Protocols, Packet Path, And Network Policy.
• 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.
