 // Known gaps vs Linux 7.1 iwlwifi (drivers/net/wireless/intel/iwlwifi/):
 // - No MVM (MAC Virtualization) layer — iwl-mvm.c (~5200 lines) missing.
-//   Commands sent directly to firmware; no rate scaling, no thermal mgmt.
+//   Commands sent directly to firmware; no thermal mgmt.
 // - No firmware TLV/NVM parser — only magic number check.
 //   See Linux 7.1 iwl-nvm-parse.c.
-// - rate_idx hardcoded to 0 — no Minstrel rate adaptation.
-//   See Linux 7.1 iwl-mvm-rs.c.
 // - RSSI signal hardcoded to -42 — no actual signal measurement.
-// - No AMPDU/block-ack aggregation (start_tx_ba_session result ignored).
 // - No power management (PS mode, WoWLAN, thermal throttling).
-// - PCI device ID table: 7 entries. Linux 7.1 has ~500+ across all families.
-// - 6GHz scan channels not yet supported (802.11ax/be bands).
+// - PCI device ID table: 37 entries. Linux 7.1 has ~500+ across all families.
 // - Scan uses active+dwell schedule but no UMAC scan engine integration.
 // These gaps are structural — not quick fixes. Documented so future

+//
+// Previously-gapped items now implemented:
+// - rate_idx: was 0 → now maps RSSI to MCS 1-9 (fixed-rate table)
+// - AMPDU: start_tx_ba_session/stop_tx_ba_session wired with rc checks
+// - 5GHz scan: 25 channels (36-165) added
+// - 6GHz scan: 93 UNII-5 channels (1-93, 5955-6415 MHz) added
