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.
• 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.

Dependency Surface

• 11n_aggr.h
• 11n_rxreorder.h

Annotation

• Immediate include surface: `11n_aggr.h`, `11n_rxreorder.h`, `wmm.h`.
• Detected declarations: `function mwifiex_is_station_ampdu_allowed`, `function mwifiex_is_ampdu_allowed`, `function mwifiex_is_amsdu_allowed`, `function mwifiex_space_avail_for_new_ba_stream`, `function mwifiex_find_stream_to_delete`, `function mwifiex_is_sta_11n_enabled`, `function mwifiex_tdls_peer_11n_enabled`.
• Atlas domain: Driver Families / drivers/net.
• Implementation status: source 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.
