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.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
• Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

• Immediate include surface: `linux/module.h`, `linux/kernel.h`, `linux/netdevice.h`, `linux/etherdevice.h`, `linux/init.h`, `linux/llc.h`, `net/llc.h`, `net/stp.h`.
• Detected declarations: `function br_device_event`, `function br_switchdev_event`, `function br_switchdev_blocking_event`, `function br_toggle_fdb_local_vlan_0`, `function br_boolopt_toggle`, `function br_boolopt_get`, `function br_boolopt_multi_toggle`, `function for_each_set_bit`, `function br_boolopt_multi_get`, `function br_opt_toggle`.
• Atlas domain: Networking Core / Sockets, Protocols, Packet Path, And Network Policy.
• Implementation status: integration implementation candidate.
• Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.

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.
