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.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• net/xfrm.h
• ../nfp_net.h
• nfd3.h

Detected Declarations

• function nfp_nfd3_ipsec_tx

Annotated Snippet

switch (l4_proto) {
		case IPPROTO_UDP:
			txd->flags |= NFD3_DESC_TX_UDP_CSUM;
			return;
		case IPPROTO_TCP:
			txd->flags |= NFD3_DESC_TX_TCP_CSUM;
			return;
		}
	}
}

Annotation

• Immediate include surface: `net/xfrm.h`, `../nfp_net.h`, `nfd3.h`.
• Detected declarations: `function nfp_nfd3_ipsec_tx`.
• Atlas domain: Driver Families / drivers/net.
• 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.
