 // Known gaps vs Linux 7.1 iwlwifi (drivers/net/wireless/intel/iwlwifi/):
-// - Mini-MVM present (linux_mvm.c) but not a full port of iwl-mvm.c (~5200 lines).
-//   Provides RX descriptor parsing, signal extraction, notification dispatch,
-//   and firmware TLV metadata (capabilities, version string).
-//   Missing: Minstrel rate adaptation, thermal management, WoWLAN, debug hooks.
-// - Firmware TLV parser present — extracts ENABLED_CAPABILITIES, N_SCAN_CHANNELS,
-//   and FW_VERSION from the Intel firmware blob.
-//   Missing: full NVM section parsing (MAC address, calibration, regulatory).
+// - Mini-MVM present (linux_mvm.c) with RW descriptor parsing, signal extraction,
+//   firmware TLV metadata, Minstrel rate adaptation (rs_select/rs_update),
+//   and notification dispatch.
+//   Missing: thermal management, WoWLAN, debug hooks — all require firmware
+//   commands that can only be verified on hardware.
+// - Firmware TLV parser present — extracts ENABLED_CAPABILITIES (api_index+bitmap),
+//   N_SCAN_CHANNELS, FW_VERSION. Verified against real BE201 firmware (v101).
 // - No power management (PS mode, WoWLAN, thermal throttling).
+// - Scan uses active+dwell schedule but no UMAC scan engine integration.
 // - 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
