Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

• Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.
• Touches IRQ or DMA behavior; this matters for the representative real-device path.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/list.h
• linux/atomic.h
• linux/netdevice.h
• linux/proc_fs.h
• linux/skbuff.h
• net/neighbour.h

Detected Declarations

• struct cxgb3_client
• struct t3cdev
• enum t3ctype

Annotation

• Immediate include surface: `linux/list.h`, `linux/atomic.h`, `linux/netdevice.h`, `linux/proc_fs.h`, `linux/skbuff.h`, `net/neighbour.h`.
• Detected declarations: `struct cxgb3_client`, `struct t3cdev`, `enum t3ctype`.
• Atlas domain: Driver Families / drivers/net.
• Implementation status: source implementation candidate.
• IRQ or DMA behavior appears here, which is relevant to the selected PCIe/NVMe device path.

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.
