v5.1 supersedes v5.0 and closes the final v5.2 implementation track (G-A4 iwlwifi spawned-mode channel contract). After v5.0 + v5.1: - G-A1 (AER/pciehp dedup): FIXED v5.0 - G-A2 (cpufreq/thermald): FIXED v5.1 - G-A3 (pcid FIFO rollover): FIXED v5.0 - G-A4 (iwlwifi spawned-mode): FIXED v5.1 (this commit) - G-A5 (driver-manager restart): FIXED v5.0 - v5.3 (initnsmgr head-of-line): FIXED v5.0 - v5.5 (boot race instrumentation): FIXED v5.0 The only remaining open items are: - v5.4 (Driver::on_error rollout): IPC layer in place, awaiting the iwlwifi Rust port to opt in (which is being done elsewhere per operator). - v5.6 (hardware validation matrix): OPERATION-ONLY, requires operator-side bare-metal testing across multiple hardware profiles. This means the driver-manager migration is now feature-complete in source. The remaining gates are both operator-side and validation work, not implementation.
