Why This File Exists
Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.
- Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.
- Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.
Dependency Surface
- No C-style include directives detected by the generator.
Detected Declarations
- No top-level syscall, struct, function, initcall, or export declaration detected by the generator.
Annotated Snippet
What: /sys/class/net/<iface>/dsa/tagging
Date: August 2018
KernelVersion: 4.20
Contact: netdev@vger.kernel.org
Description:
On read, this file returns a string indicating the type of
tagging protocol used by the DSA network devices that are
attached to this master interface.
On write, this file changes the tagging protocol of the
attached DSA switches, if this operation is supported by the
driver. Changing the tagging protocol must be done with the DSA
interfaces and the master interface all administratively down.
See the "name" field of each registered struct dsa_device_ops
for a list of valid values.Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- 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.
